摘要

本文在传质过程的乳状液膜破裂作用研究中

对1982年W.S.Ho提出的反应前沿模型所忽略的乳状液膜破裂问题

进行了探讨.考虑这些因素后

用扰动与幂级数联合解法获得了分析解.并提出有效萃取时间、萃取项、破裂泄漏项等新概念.这一工作扩大了Ho模型的应用

以及能更准确地预见萃取情况.

Abstract

An improved model for liquid membrane mass transfer has been developed. A mode) presented by W. S. Ho(1982) for diffusion controlled mass transfer into the double layer emulsions does not account for the membrane breakage. The improved model takes the membrane breakage into consideration

and is solved by power series and perturbation method. This paper discusses the rule of membrane breakage

and put forward new concepts of effective extraction time and breakage leakage

etc. This improved model predicts the extraction rates more accurater than Hos model.
