ASTM D4251-89(2003) 用电势滴定法测定阴离子表面活性剂中活性物质含量的标准试验方法

Anionic surfactants are the most widely used of the synthetic detergents. ASTM methods in current use for their determination involve two-phase aqueous/chloroform titrations with the organic dyes methylene blue (Test Method D 1681) or disulphine blue/dimidium bromide (Test Method D 3049) as indicators. One advantage of the potentiometric method is that it eliminates the use of chloroform whose use is restricted for environmental and toxicological reasons. This test method is intended for use as described in 1.1.1.1 This test method describes a potentiometric titration procedure for determining the anionic active matter in detergents. It is intended for the analysis of anionic surfactants such as detergent range alkylbenzenesulfonates, 945;-olefin sulfonates, alcohol sulfates, and alcohol ethosulfates. It has not been tested for surfactant formulations.1.2 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. Material Safety Data Sheets are available for reagents and materials. Review them for hazards prior to usage.

Standard Test Method for Active Matter in Anionic Surfactants by Potentiometric Titration

ASTM D3049-89(2016) 用氧离子滴定法合成阴离子配合剂的标准试验方法

4.1 This test method offers a means of determining anionic detergents commonly found in laundry, dishwashing, and other cleaning materials. Accurate determination of the anionic active substance is highly important in assessing the cost and effectiveness of such cleaning substances. 4.2 This test method is not affected by low molecular weight sulfonates, such as those of toluene and xylene commonly found in detergent formulations, when these substances are present up to 15 weight8201;% of active material. 1.1 This test method covers the determination of the amount of synthetic anionic ingredient in a surfactant by direct titration with a standardized cationic reagent. The test method is a simple and convenient means for the quantitative estimation of the anionic material. The end point is detected by the transfer of a colored complex from an organic solvent phase to an aqueous phase. The colored complex is formed by the addition of a solution of dye to a solution of the anionic surfactant. This complex is soluble in the organic-solvent phase and insoluble in the aqueous phase. When this solution is titrated with a standardized solution of a cationic reagent, the dye is displaced from the colored complex and, being water-soluble, migrates to the aqueous phase. Therefore, a cationic titrating solution that has been standardized against a characterized anionic agent can be used to analyze for other anionics of known molecular mass. 1.2 This test method is applicable to alkylaryl sulfonates, alkyl sulfonates, alkyl sulfates and hydroxy-sulfates, alkylphenol- and fatty alcohol ethoxy-sulfates and dialkylsulfosuccinates. It applies to active materials containing one hydrophilic group per molecule. 1.3 The analytical procedures appear in the following order:   Sections Reagents 6  Primary Standard 8  8199;Purity 8.2 8199;Alcohols 8.3 8199;Free Acid or Alkali

ISO 9101:1987 表面活性剂 界面张力的测定 滴体积法

The volume of a drop of an aqueous phase formed at the end of a vertical capillary tube is measured when it detaches from the tube in contact with the organic phase. The interfacial tension between two liquid phases is obtained by balancing the weight of the drop with the interfacial tension force supporting it and applying a correction factor. Then the interfacial tension is calculated from the volume of the falling drop, the outer capillary radius, the density difference between the two liquid phases and the acceleration due to gravity.
