| 摘 要： | 生产脱色脱酸苹果汁时,树脂碱洗液中含有大量天然L-苹果酸,研究了采用电渗析法脱盐回收废液中的苹果酸,及其对苹果酸废液脱盐的工艺条件。将废液pH调至4.0,工作电流11A下循环脱盐2 h,脱盐率达99%以上,含Na 11 821 mg/L的废液脱盐至含Na 42.88 mg/L,其中L-苹果酸损失18.94%,基本达到分离要求,表明了电渗析对苹果酸废液的脱盐是切实可行的。

| Abstract: | In the pro duction of color and acid free apple juice,the effluent of resin was rich in natural L-malic acid.The desalination of malic acid effluent by electro dialysis was studied.The optimum technological conditions were found out.Under the condition of pH 4.0,electric current 11A and 2 hours circulation,the desalination rate reached more than 99%.Na+ in the effluent could be desalted from 11 821 mg/L to 42.88 mg/L,and the L-malic acid in the effluent reduced by 18.94%.The results proved that electro dialysis was a feasible method for malic acid effluent desalination. |
