바이폴라막 전기투석에 의한 유기산 회수에 관한 모델링

Abstract

This paper studied the recovery of organic acid from organic acid salt by using bipolar membrane elec-trodialysis. Acetic acid and lactic acid was used as for organic acid. Organic acid concentration, sodium hydroxide con-centration and pH values were measured at various current density. Organic acid salt was effectively converted toorganic acid and sodium hydroxide. Based on the experimental results, mathematical models were developed, in whichtime changes in ion balance were considered. Model predictions of organic acid concentration, sodium hydroxide con-
