ASTM-D6174 › Standard Test Method for Inorganic Sulfate in Surfactants by Potentiometric Lead Titration (Withdrawn 2015)
The following bibliographic material is provided to assist you with your purchasing decision:
Scope
1.1 This test method describes a potentiometric titration procedure for determining the inorganic sulfate content of surfactants. It is intended for the analysis of -olefin sulfonates, alkane sulfonates, alcohol sulfates, alcohol ether sulfates, alkylbenzenesulfonates, and the like.
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.
Significance and Use
Anionic surfactants, such as those listed in 1.1, commonly are used in detergent formulations. Their acceptability for use depends on their purity. Sulfate content, as measured by this test method, can be used to estimate the purity of an anionic surfactant under test.
