【Abstract】 The laboratory procedure of the new decolouration technique for synthetlc medicines with absorption ion exchange resin was reported,which can be used to replace the tranditional technique with actived carbon. The choice of type, the recovery, and the decolouration condition of ion exchange were investigated in detail.The new technique was successful in declouration of caffeine product. Compared with actived carbon decolouration, the resin declouration is simple in procedure without enviroment pollution ,the quality of product is good.更多还原
