| Abstract: | The method of separation and purification of lactic acid (LA) produced in the fermentation of corn was studied.The LA can be separated and purified well by ion exchange resin and concentrated by the technology of vacuum distillation.The effects of temperatures and flow rates in the exchange process were studied.The concentrations of LA in the whole process were monitored by HPLC. |
