摘　　要：随着水处理剂聚丙烯酰胺在污水处理中大量使用,产品质量参差不齐,尤其是氯化物含量有时严重超标,现有标准GB/T 17514—2017中规定的比色法已不能准确判断其氯化物含量。通过汞量法和银量法两种测定氯化物通用方法的比较,选择汞量法测定聚丙烯酰胺中的氯化物,可快速准确判断其氯化物含量,了解聚丙烯酰胺产品质量,具有一定实用和可操作性。As the water treatment agent polyacrylamide is widely used in sewage treatment,the product quality varies widely,especially the chloride content sometimes exceeds the standard seriously.The colorimetric method specified in current standard GB/T17514-2017 can no longer determine the chloride content accurately.In this paper,the volumetric titration method can be used to quickly and accurately determine the chloride content and understand the quality of polyacrylamide products,which is practical and operable.
