两相滴定法在石油羧酸盐表面活性剂体系中的应用

Application of Biphase Titration in Petroleum Carboxylate Surfactant System

建立了测定石油羧酸盐表面活性剂体系中非离子表面活性剂浓度的两相滴定法。对非离子表面活性剂进行了分离、富集并测定其浓度，取得了较好的效果。

Biphase titration for determination nonionic surfactant in petroleum carboxylate surfactant system is established．Nonionic surfactant is separated and enriched． And getting satisfactory effect for determination of nonionic surfactant．
