Abstract
Decomposition of lactic acid/trimetylamine compound through heating is difficult in the complexation extraction process to recover lactic acid from ferment broth and to regenerate solvent.Bipolar membrane electrodialysis can be used to achieve this goal.Experiment results show that pure lactic acid can be obtained with more than 90% recovery.
