摘　　要：利用树脂吸附法对黄连素模拟废水进行了试验研究,对5种大孔吸附树脂进行初步筛选,从中优选出最佳吸附树脂(大孔树脂H103)。考察了pH和树脂投加量对吸附效果的影响,绘制了动力学曲线和吸附等温线。结果表明:在黄连素浓度为1 000 mg/L,最佳初始pH为7.0的条件下,树脂最佳投加量为3.0 g。在最佳pH条件下,吸附等温线可用Freundlich等温吸附方程描述。The removal of berberine from synthetic pharmaceutical wastewater by polymeric adsorption resins was investigated.The optimal polymeric adsorbent was selected as H103 based on the comparison of berberine removal rates.The effects of pH and the amount of polymeric resin on the adsorption of berberine were explored.Besides,the diffusion within spherical particles model fitting curves and the adsorption isotherms of berberine were tested.The results showed that the optimum pH was 7.0 when the simulated berberine wastewater concentration was 1 000 mgL.Under optimum pH,the best amount of resin is 3.0 g.Adsorption isotherm of berberine could be described by Freundlich equation.
