ASTM D3454-11 水中镭-226的标准检测方法

The most prevalent of the five radium isotopes in ground water, having a half life greater than one day, are 226Ra and 228Ra. These two isotopes also present the greatest health risk compared to the other naturally occurring nuclides of equal concentrations if ingested via the water pathway. Although primarily utilized on a water medium, this technique may be applicable for the measurement of the 226Ra content of any media once the medium has been completely decomposed and put into an aqueous solution. The general methodology and basis of this technique are similar to the methodology “226Ra in Drinking Water (Radon Emanation Technique)” as described in the document EPA-600//4-80-032. 1.1 This test method covers the measurement of soluble, suspended, and total radium-226 in water in concentrations above 3.7 × 10−3 Bq/L. This test method is not applicable to the measurement of other radium isotopes. 1.2 This test method may be used for quantitative measurements by calibrating with a radium-226 standard, or for relative measurements by comparing the measurements made with each other. 1.3 This test method does not meet the current requirements of Practice D2777. 1.4 The values stated in SI units are to be regarded as the standard. The inch-pound units given in parentheses are for information only. 1.5 Hydrofluoric acid (HF) is very hazardous and should be used in a well-ventilated hood. Wear rubber gloves, safety glasses or goggles, and a laboratory coat. Avoid breathing any HF fumes. Clean up all spills promptly and wash thoroughly after using HF. 1.6 This standard does not purport to address all of the other safety concerns, if any, associated with its use.

ASTM D4691-11 火焰原子吸收分光光度法测定水中元素的标准操作规程

Elemental constituents in water and wastewater need to be identified to support effective water quality monitoring and control programs. Currently, one of the most widely used and practical means for measuring concentrations of elements is by atomic absorption spectrophotometry. The major advantage of atomic absorption over atomic emission is the almost total lack of spectral interferences. In atomic emission, the specificity of the technique is almost totally dependent on monochromator resolution. In atomic absorption, however, the detector sees only the narrow emission lines generated by the element of interest.1.1 This practice covers general considerations for the quantitative determination of elements in water and waste water by flame atomic absorption spectrophotometry. Flame atomic absorption spectrophotometry is simple, rapid, and applicable to a large number of elements in drinking water, surface waters, and domestic and industrial wastes. While some waters may be analyzed directly, others will require pretreatment. 1.2 Detection limits, sensitivity, and optimum ranges of the elements will vary with the various makes and models of satisfactory atomic absorption spectrometers. The actual concentration ranges measurable by direct aspiration are given in the specific test method for each element of interest. In the majority of instances the concentration range may be extended lower by use of electrothermal atomization and conversely extended upwards by using a less sensitive wavelength or rotating the burner head. Detection limits by direct aspiration may also be extended through sample concentration, solvent extraction techniques, or both. Where direct aspiration atomic absorption techniques do not provide adequate sensitivity, the analyst is referred to Practice D3919 or specialized procedures such as the gaseous hydride method for arsenic (Test Methods D2972) and selenium (Test Methods D3859), and the cold vapor technique for mercury (Test Method D3223). 1.3 Because of the differences among various makes and models of satisfactory instruments, no detailed operating instructions can be provided. Instead the analyst should follow the instructions provided by the manufacturer of a particular instrument. 1.4 The values stated in either SI or inch-pound units are to be regarded as the standard. The values given in parentheses are for information only. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

This test method has been developed by US EPA Region 5 Chicago Regional Laboratory (CRL). The N-methyl carbamate (NMC) pesticides: aldicarb, carbofuran, methomyl, oxamyl, and thiofanox have been identified by EPA as working through a common mechanism. These affect the nervous system by reducing the ability of enzymes. Enzyme inhibition was the primary toxicological effect of regulatory concern to EPA in assessing the NMC’s food, drinking water, and residential risks. In most of the country, NMC residues in drinking water sources are at levels that are not likely to contribute substantially to the multi-pathway cumulative exposure. Shallow private wells extending through highly permeable soils into shallow, acidic ground water represent what the EPA believes to be the most vulnerable drinking water. Aldicarb sulfone and aldicarb sulfoxide are breakdown products of aldicarb and should also be monitored due to their toxicological effects. This method has been investigated for use with reagent, surface, and drinking water for the selected carbamates: aldicarb, aldicarb sulfone, aldicarb sulfoxide, carbofuran, methomyl, oxamyl and thiofanox.1.1 This test method covers the determination of aldicarb, aldicarb sulfone, aldicarb sulfoxide, carbofuran, methomyl, oxamyl, and thiofanox (referred to collectively as carbamates in this test method) in water by direct injection using liquid chromatography (LC) and detected with tandem mass spectrometry (MS/MS). These analytes are qualitatively and quantitatively determined by this method. This method adheres to multiple reaction monitoring (MRM) mass spectrometry. 1.2 The Detection Verification Level (DVL) and Reporting Range for the carbamates are listed in Table 1. 1.2.1 The DVL is required to be at a concentration at least 3 times below the Reporting Limit (RL) and have a signal/noise ratio greater than 3:1. Fig. 1 displays the signal/noise ratios of the primary single reaction monitoring (SRM) transitions, and Fig. 2 displays the confirmatory SRM transitions at the DVLs for the carbamates. 1.2.2 The reporting limit is the concentration of the Level 1 calibration standard as shown in Table 2 for the carbamates. 1.3 Units8212;The values stated in SI units are to be regarded as standard.

This test method has been developed by US EPA Region 5 Chicago Regional Laboratory (CRL). Bromadiolone, brodifacoum, diphacinone and warfarin are rodenticides for controlling mice, rats, and other rodents that pose a threat to public health, critical habitats, native plants and animals, crops, food and water supplies. These rodenticides also present human and environmental safety concerns. Warfarin and diphacinone are first-generation anticoagulants, while bromadiolone and brodifacoum are second-generation. The anticoagulants interfere with blood clotting, and death can result from excessive bleeding. The second-generation anticoagulants are especially hazardous for several reasons. They are highly toxic and persist a long time in body tissues. The second-generation anticoagulants are designed to be toxic in a single feeding, but time-to-death occurs in several days. This allows rodents to feed multiple times before death, leading to carcasses containing residues that may be many times the lethal dose. This method has been investigated for use with reagent, surface, and drinking water for the selected rodenticides.1.1 This procedure covers the determination of bromadiolone, brodifacoum, diphacinone and warfarin (referred to collectively as rodenticides in this test method) in water by direct injection using liquid chromatography (LC) and detected with tandem mass spectrometry (MS/MS). These analytes are qualitatively and quantitatively determined by this method. This method adheres to multiple reaction monitoring (MRM) mass spectrometry. 1.2 The Detection Verification Level (DVL) and Reporting Range for the rodenticides are listed in Table 1. 1.2.1 The DVL is required to be at a concentration at least 3 times below the Reporting Limit (RL) and have a signal/noise ratio greater than 3:1. Fig. 1 displays the signal/noise ratios of the primary single reaction monitoring (SRM) transitions, and Fig. 2 displays the confirmatory SRM transitions at the DVLs for the rodenticides. 1.2.2 The reporting limit was calculated from the concentration of the Level 1 calibration standard, as shown in Table 4, accounting for the dilution of a 40 mL water sample up to a final volume of 50 mL with methanol to ensure analyte solubility. 1.3 Units8212;The values stated in SI units are to be regarded as standard.

Radioactive iron is produced by neutron activation of stable iron. Its concentration in reactor coolant is used to monitor the corrosion of reactor parts such as reactor fuel-cladding material and reactor structural components. This technique effectively removes other activation and fission products such as isotopes of iodine, zinc, manganese, cobalt, and cesium by the addition of hold-back carriers and an anion exchange technique. The fission products (zirconium-95 and niobium-95) are selectively eluted with hydrochloric-hydrofluoric acid washes. The iron is finally separated from Zn+2 by precipitation of FePO4 at a pH of 3.0.1.1 This test method covers the determination of 55Fe in the presence of 59Fe by liquid scintillation counting. The a-priori minimum detectable concentration for this test method is 7.4 Bq/L. 1.2 This test method was developed principally for the quantitative determination of 55Fe. However, after proper calibration of the liquid scintillation counter with reference standards of each nuclide, 59Fe may also be quantified. 1.3 This test method was used successfully with Type III reagent water conforming to Specification D 1193.

ASTM D5543-09 水中低水平溶解氧的标准试验方法

Dissolved oxygen is detrimental in certain boiler and steam cycles because it may accelerate corrosion. Concentrations above 10 μg/L are unacceptable in many high-pressure boiler systems. The efficiency of dissolved oxygen removal from boiler feedwater by chemical or mechanical means, or both, is determined by measuring the concentration before and after the process. The measurement is also made to check for air leakage into the boiler system. The oxygen treatment method for boiler corrosion reduction requires injection of oxygen into the boiler feedwater. The resulting oxygen level is monitored for control purposes.1.1 This test method covers the determination of low-level (<100μ g/L) dissolved oxygen in thermal-cycle steam condensate, deaerated boiler feedwater, boiler water, and deaerated deionized water.

N-Ethyldiethanolamine, N-methyldiethanolamine and triethanolamine are Schedule 3 compounds under the Chemical Weapons Convention (CWC). Schedule 3 chemicals include those that have been produced, stockpiled or used as a chemical weapon, poses otherwise a risk to the object and purpose of the CWC because they possess such lethal or incapacitating toxicity as well as other properties that might enable it to be used as a chemical weapon, poses otherwise a risk to the object and purpose of the CWC by virtue of it’s importance in the production of one or more chemicals listed in Schedules 1 or 2, or it may be produced in large commercial quantities for purposes not prohibited under the CWC. Ethanolamines have a broad spectrum of applications. They are used to produce adhesives, agricultural products, cement grinding aids, concrete additives, detergents, specialty cleaners, personal care products, gas treatments, metalwork, oil well chemicals, packaging and printing inks, photographic chemicals, rubber, textile finishing, urethane coatings, textile lubricants, polishes, pesticides, and pharmaceuticals. Ethanolamines are readily dissolved in water, biodegradable and the bio-concentration potential is low. This method has been investigated for use with reagent and surface water.1.1 This procedure covers the determination of diethanolamine, triethanolamine, N-methyldiethanolamine and N-ethyldiethanolamine (referred to collectively as ethanolamines in this test method) in surface water by direct injection using liquid chromatography (LC) and detected with tandem mass spectrometry (MS/MS). These analytes are qualitatively and quantitatively determined by this method. This method adheres to single reaction monitoring (SRM) mass spectrometry. 1.2 This test method has been developed by US EPA Region 5 Chicago Regional Laboratory (CRL). 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4 The Detection Verification Level (DVL) and Reporting Range for the ethanolamines are listed in Table 1. 1.4.1 The DVL is required to be at a concentration at least 3 times below the Reporting Limit (RL) and have a signal/noise ratio greater than 3:1. Fig. 1 displays the signal/noise ratios at the DVLs and at higher concentrations for N-methyldiethanolamine. 1.4.2 The reporting limit is the concentration of the Level 1 calibration standard as shown in Table 2 for diethanolamine, triethanolamine, and N-ethyldiethanolamine and Level 2 for N-methyldiethanolamine. The reporting limit for N-methyldiethanolamine is set at 50 μg/L due to poor sensitivity at a 5 μg/L concentration which did not meet the DVL criteria. The DVL for N-methyldiethanolamine is at 10 μg/L, which forces a raised reporting limit (chromatograms are shown in Fig. 1). However, the multi-laboratory validation required a spike of all target analytes at 25 μg/L. The mean recovery for N-methyldiethanolamine at this level was 88 % as shown in Table 3. If your instrument’s sensitivity can meet the requirements in this test method, N-methyldiethanolamine may have a 25 μg/L reporting limit. 1.5 This standard does not purport to address all of the safety concerns, if ......

ASTM D3082-09 水中硼的标准试验方法

Because boron can be both essential and deleterious to plant growth, and because ingestion of large amounts can affect the central nervous system in humans, a method is required to determine its concentration in potable, natural, and wastewaters. This test method provides a means of determining the boron concentration of these waters. The holding time for the samples may be calculated in accordance with Practice D 4841. Boric acid is used for chemical shim control of neutron flux in a nuclear reactor. This test method serves to determine if the boron concentration is within acceptable limits.1.1 This test method covers the determination of boron in water and wastewaters by the curcumin colorimetric-extraction method in concentrations between 0.1 and 1.0 mg/L. The range can be extended by dilution of the sample. 1.2 Only dissolved boron is determined. This test method requires that the water sample be filtered through a 0.45-μm membrane filter before analysis. 1.3 This test method is a colorimetric method that is very sensitive to low concentrations of boron in water and requires a relatively small sample volume for analysis. 1.4 Precision and bias were obtained on natural and wastewaters. It is the user's responsibility to ensure the validity of this test method for waters of untested matrices. 1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

ASTM D4658-09 水中硫离子的标准试验方法

Sulfide ion is found in ground waters and wastewater, causing odor and corrosion problems. If acidified, these waters can release hydrogen sulfide, which is extremely toxic even at low levels. This test method provides a means for interference-free measurement of free sulfide ion. Note 18212;Sulfide forms complexes with hydrogen ions (HS1− and H2S). In addition, sulfide ion forms soluble complexes with elemental sulfur (S22−, S32−, S42−, etc.), tin, antimony, and arsenic ions.1.1 This test method uses an ion-selective electrode to determine sulfide ion in water. The test method is applicable in the range from 0.04 to 4000 mg/L of sulfide. 1.2 Precision data presented in this test method were obtained using reagent water only. It is the user's responsibility to ensure the validity of this test method for untested types of water. 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Sulfide samples, when acidified, can release highly toxic hydrogen sulfide gas. For a specific precautionary statement, see Note 2.
