Scope

Scope: This document specifies the method for detecting residual anionic detergents in recycling buckets. This document is applicable to bottled water production enterprises for determining the residual amount of anionic detergents in buckets after the buckets are cleaned and ready for filling with finished water. This document uses the methylene blue spectrophotometric method to determine the residual anionic detergents in recycling buckets. Phenols, organic sulfates, sulfonates, phosphates, as well as large amounts of chlorides, silver nitrate, and thiocyanates in water can all lead to inflated test results. Main technical content: The method for detecting residual anionic detergents in recycling buckets.
