摘要
目的：采用絮凝剂壳聚糖用于“抗感灵”提取液的澄清除杂。方法：对絮凝条件进行了优化，并同醇的效果做了比较。结果：最佳的絮凝条件，壳聚糖加入量为0．48g／L，温度为40℃，PH值为4．0。结论：壳聚糖絮凝法不仅澄清除杂效果好，且成本低，安全无毒，可代替醇沉法用“抗感灵”提取除杂工艺。
objective：To clarify KangGanLing via Chitosan Flocculation.Methods：The operating conditions were optimized and the results were compared with that of ethanol subsiding.Results：The optimized conditions were： .0.48g/L Chitosan flocculating agent was added at 40℃ and PH4.0.Conclusion： Chitosan flocculating method was efficient on the clarification of KangGanLing ,economic and safe and can replace ethanol subsiding method.
