GB/T 15916-2012 《Surface active agents - Determination of chelating agent content - Titrimetric method》 Related products

GB/T 15916-2012 The Titrimetric method is used to determine the content of chelating agents in surfactants, which is suitable for all kinds of surfactant products. This method is based on the complexation reaction of chelating agents with specific metal ions, and calculates the content of chelating agents by titrating the metal ion solution according to its dosage. The standard specifies the specifications of Burette and other instruments, and specifies the preparation of related reagents. Detail the processing steps of surfactant samples, such as dissolving the sample, separating interfering substances and other operation points. Standardize the operation process in the titration process, including titration speed control and end point judgment methods. According to this standard, the content of chelating agents can be accurately determined, which helps surfactant mass monitoring and related industrial production applications.
