摘要
本文分别以十二烷基硫酸钠（ＳＤＳ）和十六烷基三甲基溴化铵（ＣＴＡＢ）作滴定剂，相互进行电导滴定，从得到的溶液电导率与滴定剂体积的电导滴定曲线，可以确定滴定终点，从而求出ＳＤＳ或ＣＴＡＢ的浓度，同时对低碳链离子型表面活性剂也能测定，这是电导滴定法优于两相滴定法之处。本文还将电导滴定法用于家用洗衣粉中阴离子表面活性剂的测定，结果与亚甲基蓝两相滴定法吻合。
The conductimetric titration of sodium laury sulfate (SDS) and cetyl trintethyl ammoniurn bromide(CTAB) was studied. The end points of titration could be determined through the conductimetrit titration curves. So the concentration of SDS or CTAB is obtained. Meanwhile the concentration of anionic surfactant in washing powder was determined by this method.
