液膜法提取pd(Ⅱ)的传质模型

Mass-Spreading Model of Extracting pd(Ⅱ)by Using Liquid Film Method

本文通过萃取一反萃取实验确定了TOA液膜体系萃取和反萃取pd(Ⅱ)的化学反应方程式;通过测定外水相经液膜提取前后H^+和cl^-浓度的变化确定了液膜迁移机理。

The article determines the chemical reaction equation of extraction and anti-extraction of pd(Ⅱ) by using TOA liquid film system through the extraction anti-extraction tests. It determines the mechanism of liquid film movement through measuring changes in density of H+ and cl- of outer water form passing liquid film extraction.
