摘要
本文以自制四苯硼酸根电极为指示电极,对电位滴定法测定非离子表面活性剂进行了研究,该法适用于超浓缩洗衣粉中非离子表面活性剂含量的测定,且操作简单、快速、精度高。
The content determination of nonionics by potentiometry with tetraphenyl borate (TPB) as indicating electrode was investigated.The resuls obtained indicated that the jump at the end point of titration was 20mv over that of reported, the variation coefficient was<1.7%, and relative error was<5.0% This method can be applied to determine the content of nonionics in concentrated detergent powders.
