摘　　要：采用同位素示踪原子法研究了非离子表面活性剂在无机盐存在下从水相到油相传质的规律，发现无机盐能强烈地影响非离子表面活剂Ａｐ型和Ｓｐ型的传质行为，而且因无机盐性质的不同，表面活性剂结构的差异，传质行为亦会有很大的不同。另外，利用此技术研究解决了连续定量测定微量表面活性剂的问题，为系统研究表面传质问题开辟了一个新方法。Mass of transfer are measured in succession using liquid scintillation counting technique.Transfer of Ap and Sp series of labelled nonionic surfactants from water phase into oil phase have been studied in the presence of salts.Compared to mass of transfer in the absence of salt,mass of transfer of Ap and Sp series of surfactants is increasing with the increasing of salt con centration in the presence of NaCl、KCl、Na 2SO 4 and Na 2CO 3.In the presence of CaCl 2 and MgCl 2,mass of transfer of Ap251 and Ap281 is decreased with the increasing of salt concentration in the lower salt concentration region,while mass of transfer of Ap251 and Ap281 is increasing as salt concentration is increasing in the higher salt concentration.In the presence of CaCl 2 and MgCl 2,mass of transfer of Sp161 and Sp165 is increasing with the increasing of salt concentration in the lower salt concentration region,while mass of transfer of Sp161 and Sp165 is decreased as salt concentration is increasing in the higher salt concentration.In this paper,the effects of salts on transfer have been discussed.
