摘要
探讨了电导滴定法测定壬基酚聚氧乙醚磷酸酯中单、双酯及磷酸的含量。本法是基于该酸性酯在75％乙醇溶液中与NaOH溶液发生定量反应。本法简便、准确、快速、重现性好，且与混合指示剂法相比较，结果十分接近。
The determination method of mono - ester, di - ester and phosphori acid in phosphate polyoxyethylene nonyiphenol by conductometeic titration was investigated, with 75% alcohol used as the solvent of the sample, NaOH solution used as the titrant. It was simple accurate rapid and precise,compared with double indicator method.
