探讨了大孔吸附树脂DM-130对甘草酸的吸附性能及原液浓度、pH值、流速对此树脂吸附性能的影响.结果表明,DM-130树脂对甘草酸的吸附性能好,易于洗脱,分离效果好,产品纯度可达94.676%;正交试验表明,pH为5.4±,原液浓度为10 mg/ml,以2 BV/h的流速为最佳处理;洗脱液采用3 BV 10%的乙醇最经济.

The adsorption and desorption behavior of DM-130 resin to glycyrrhizic acid and the effect fectors including solution concentration,pH as well as flow rate for such behavior were studied in this paper.The results indicated that DM-130 resin possesses the highest adsorption capacity among the resin studied and the easiest desorption property.The purity of glycyrrhizic acid can be reached as high as 94 676%.The orthogonal experiments suggested that for the purification the optimal pH at ±5 4,the solution concentration at 10 mg/ml and the flow rat...
