Abstract
본 연구에서는 유기산염으로부터 유기산으로의 변환을 2실 배열 공정의 바이폴라막 전기투석을 이용하여 행하였다. 유기산으로 아세트산과 젖산을 사용하였으며, 유기산의 농도, 가성소다의 농도 그리고 pH 값들을 전류밀도에 따라 측정하였다. 그 결과 유기산염은 효과적으로 유기산으로 전환되었을 뿐만 아니라, 잔여 Na+ 이온을 수산화나트륨의 형태로 회수할 수 있었다. 실험 결과를 바탕으로 이온 평형을 고려하여 수학적인 모델을 확립하였다. 시간에 따른 유기산의 농도, 가성소다의 농도 그리고 pH 값의 모델식은 실험 데이터와 잘 일치하였다.
This paper studied the recovery of organic acid from organic acid salt by using bipolar membrane electrodialysis. Acetic acid and lactic acid was used as for organic acid. Organic acid concentration, sodium hydroxide concentration and pH values were measured at various current density. Organic acid salt was effectively converted to organic acid and sodium hydroxide. Based on the experimental results, mathematical models were developed, in which time changes in ion balance were considered. Model predictions of organic acid concentration, sodium hydroxide concentration and pH values were in good agreement with the experimental data.
