摘要
应用非水电位滴定法测定了废水中各种烷基磷酸酯钾盐及其单、双酯盐。方法的变异系数分别为２．３％和７．８％（ｎ＝１２）。本法可有效地消除非离子表面活性剂的干扰，适用于化纤油剂的质量检验和上油槽中油剂浓度的测定。
Mono-and di-esters of various potassium alkylphosphates in wastewater are determined respectively by nonaqueous potentiometric titration method without separation. The coefficients of variation are 2.3% and 7.8% (n=12)respectively. The interference of nonioic surfactants can be effectiviy eliminated. The method was applied to the determination of finishing solution in both and wastewater in,fiber production.
