摘要
采用732和D30l树脂对发酵液提取过程中的一次母液进行分离提纯。通过动态实验研究了对一次母液的分离效果,732强酸性树脂对镁离子杂质去除率达96%以上,D301弱碱性树脂几乎可以把一次母液中阴离子杂质除尽,而衣康酸的损失量小于1%。
The method of separation from Itaconic acid fermentation broth by ion exchangeresins was studied. Some main technology conditions were tested and discussed by experiment of dynamic state. Rate of eliminating cation impurity of 732 strong acid exchange resin can reach 96%. D301 weak basic exchange resin eliminated most anion foreign matter. The loss of Itaconic acid is less 1%.
