水处理药剂HEDP与PBTCA入厂质量检验中存在的问题及探讨

The Problems and Approaches Presenting in the Quality Assurance of Water Treatment Chemicals HEDP and PBTCA

水处理药剂羟基乙叉二膦酸(HEDP)与2-膦酸基-1, 2, 4-三羧酸丁烷(PBTCA)的质量检验标准中分析原理相同,分析方法相似,为了更有效地区分两者,根据它们总磷含量及阻垢性质的不同,以总磷分析及阻垢试验作为辅助检测手段。

The analysis principle of HEDP is same to PBTCA and their analysis of approach is analogical.To discriminate HEDP from PBTCA effectively,determination of total phosphate and the appraise of their scale-prevented ability is accessorial measure according to the difference of total phosphate and scale-prevented ability between HEDP and PBTCA.
