METHOD AND APPARATUS FOR ELIMINATING ORGANIC ACIDS BY ELECTRODIALYSIS

摘要

PROBLEM TO BE SOLVED: To provide a method for efficiently eliminating organic acids by electrodialysis from an aqueous solution containing organic acids. SOLUTION: This method for eliminating organic acids by electrodialysis from an aqueous solution containing organic acids uses an anion-exchange membrane of which the permeation coefficient of tetraethylene glycol is 0.02 g/(hr.m<2> .(g/L)).
