전기투석에 의한 유기산 혼합물로부터 숙신산의 분리
Separation of Succinic Acid from Organic Acid Mixture Using Electrodialysis
김상헌, 이병철
혼합유기산으로부터 숙신산의 분리를 단극 분리막을 사용한 탈염전기투석장치를 이용하여 행하였다. 전류효율, 회수율, 에너지소요량, 분리비 등의 변화를 pH 값과 초기농도비에 따라 측정하였다. 숙신산의 분리는 숙신산과 아세트산의 이온화율, 분자량, 이온전도도, 전자가 크기 그리고 초기농도비 등으로 해석될 수 있었다.
This paper studied succinic acid recovery from organic acid mixture by using mono-polar membrane electrodialysis. Current efficiency, solute recovery efficiency, energy consumption, and separation factor were measured at various pHs and concentration ratios. The separation factor of succinic acid could be interpreted in terms of ionization degree, molecular weight, ionic conductance, average charge, and initial feed composition.
Keywords: Succinic Acid; Acetic; Acid; Electrodialysis; Separation Factor; Ionic Fraction; pH
