ASTM-D4608 › Standard Test Method for Citrate in Detergents
The following bibliographic material is provided to assist you with your purchasing decision:
Scope
1.1 This test method covers a potentiometric titration procedure for the determination of citrate in liquid and powder detergents.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.3 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. Specific safety precautions are given in Section 8.
Significance and Use
4.1 This test method is suitable in research, development, and manufacturing control to monitor the level of citrate, a sequestering agent, in powder and liquid detergents.
4.2 Accurate determination of sequestering agent is important in evaluating cost and performance of detergent products.
