Magnetic resin was prepared by chemical coprecipitation method,the effects of concentration of motherliquor、pH value of solution、adsorption temperature and time on adsorption rate were investigated by single factor test and orthogonal test,taking the adsorption rate of berber-ine as an index,and compared with the unmagnetized D151 resin.The test results show that,the optimum adsorption conditions are as follows:the concentration of mother liquor is 0.015 mg/mL,pH value of solution is 8,the temperature is 35℃,the adsorption time is 2.5 h,the adsorp-tion rate of magnetic D151 resin is as high as 91.11%,and the adsorption rate of unmagnetized D151 resin is 85.76%.Magnetic modified D151 cation exchange resin is used for the separation of Berberine from Phellodendron amurense with high adsorption rate and simple process.
