QB/T 4970-2016 Surface active agents.Determination of anionic surfactant in raw materials and formulated products.Potentiometric titration method (English Version)
This standard specifies the potentiometric titration method for the determination of anionic surfactants in surfactant raw materials and products manufactured according to the formula. This standard is applicable to the analysis of anionic surfactants. See Appendix A for specific surfactant types. If the analysis results are expressed in terms of mass fraction, the average relative molecular mass of the anionic surfactant is known or predetermined. This standard does not apply to determinations in the presence of cationic surfactants.
