BS ISO 23697-1:2023 水质 使用小型密封管测定水中总结合氮 (ST-TNb) 二甲基苯酚显色反应

1   Scope This document specifies a method for the determination of total bound nitrogen (ST-TN b ) in water of various origins: groundwater, surface water, and wastewater, in a measuring range of concentration generally between 0,5 mg/l and 220 mg/l of ST-TN b using the small-scale sealed tube method. Different measuring ranges of small-scale sealed tube methods can be required. The measuring ranges can vary depending on the type of small-scale sealed tube method of different manufacturers. It is up to the user to choose the small-scale sealed tube with the appropriate application range or to adapt samples with concentrations exceeding the measuring range of a test by preliminary dilution. NOTE The results of a small-scale sealed tube are most precise in the middle of the application range of the test. All small-scale sealed tube methods are based on a heated alkaline potassium persulfate oxidation in a heating block. Different digestion temperatures, 100 °C or 120 °C or 170 °C, and different digestion times are applicable. Dimethylphenol colour reactions are applied, depending on the typical operating procedure of the small-scale sealed tube used, see Clause 9.

Volumetric and spectrophotometric methods for the determination of cyanide in thiocyanate-containing wastewater

ASTM D8083-16(2023) 通过高温催化燃烧和化学发光检测计算水中总氮和总凯氏氮（TKN）的标准试验方法

1.1 This test method covers the determination of total nitrogen (TN) and total dissolved nitrogen (TDN) in surface water, seawater, groundwater, wastewater, and wastewater effluents in the range from 0.2 mg ⁄L N to 10 mg ⁄L N. Concentrations from 10 mg ⁄L to 500 mg ⁄L are possible when used in conjunction with manual or automatic dilution, or automatic injection of less sample volume. The EPA 40 CFR Part 136 Appendix B Method Detection Limit (MDL) is 0.05 mg ⁄L N. Higher concentrations may be determined by sample dilution. Lower concentrations may be possible by injecting larger sample volumes. Follow the manufacturer’s instructions. 1.2 The sample is injected onto a platinum catalyst heated at ≥720 °C. The sample converts into a gaseous phase and is forced through a layer of catalyst ensuring conversion of all nitrogen containing compounds to nitrogen oxide (NO). Reaction with ozone converts the NO to an exited NO2. As the excited NO2 returns to the ground state, it emits radiation that is measured photo-electrically. 1.3 Total and dissolved organic carbon analysis by Test Method D7573 can be analyzed at the same time on the same sample simultaneously using a properly equipped analyzer. (See Appendix X1 for an example of simultaneous TOC data.) 1.4 This test method quantitatively recovers nitrogen from a large range of organic and inorganic nitrogen compounds (see Table 1 and Table 2). The test method does not measure nitrogen gas (N2). It is the user’s responsibility to ensure the validity of this test method for waters of untested matrices. 1.5 This test method is applicable only to nitrogenous matter in the sample that can be introduced into the reaction zone. The syringe needle or injector opening size generally limits the maximum size of particles that can be so introduced. Optional automatic sample homogenization may be used. 1.6 This test method is performance based. You may make modifications that improve the test method’s performance but do not change the oxidation or detection technique. 1.7 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.8 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.9 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
