Question

Recovery of lactic acid from sodium lactate by ion substitution using ion-exchange membrane

Answer 1

Explanation:

recovered lactic acid from sodium lactate by conventional electrodialysis using bipolar membranes instead of anion-exchange membranes.

Answer 2

Answer:

With the elapsed time, the concentration of sodium ions decreased in the feed solution, while due to the pH increase the lactic acids were converted to lactate ions and transported through the anion-exchange membrane. Thus a significant loss of lactic acid occurred in the CED operation.
