离子膜电解传质过程动态模拟初探

Simulation of the Matter Migrating Process in Membrane-electrolysis

在直流电场中 ,对位于阳极室的CuSO4溶液在阳离子交换膜作用下溶液内离子的传质过程进行动态模拟 .在理论分析和实验的基础上 ,对实验现象进行了描述与理论分析 ,对电解产物初步分析 ,发现随电解条件的不同 ,除阴极有金属铜的还原外 ,阴极表面和阴极室中还存在Cu(OH) 2 、CuOH、CuO、Cu2 O和CuSO4·Cu(OH) 2 沉淀 .最后 。

In direct electric current, it simulated dynamically the process in which the Ion Cu 2+ migrated the cation-exchange membrane from catholyte. On the base of theory analyzing and experiment ,it described and analyzed the experiment phenomena and found that the metal Cu reduced on the negative electrode pole and reformed as Cu(OH) 2 ,CuOH,Cu 2O,CuSO 4·CuOH in the anolyte. At last, the paper analyzed the reaction mechanism.
