Treatment of low concentration SO_2 absobing solution using tree-cell electrodialysis stack by membrane electrodialysis

Qixiu Zhang

Abstract

A method of treating low concentration soluton absorbing SO2 by membrane electrodialysis was proposed.Operation process and principle were provided.Electrodialysis mechanism and ions transfer were fully and detailed clarified.Selections of composition materials were discussed.. For example,F4112 cation exchange membrane and β-PbO2 anode were selectied in the system.The optimal concentration of sulfuric acid in the anode cell,stream recycle way,and the relation beteen oporation current dencity and current effeciency were gained.The experimental results show that this method is promissing one for treating low concentration SO2 absorbing solutions.
