| 摘 要： | 选择18种大孔树脂,比较其对虎杖白藜芦醇的吸附和解吸性能,筛选出较优的4种大孔树脂,通过研究其静态吸附动力学特性,进一步筛选出适合分离虎杖白藜芦醇的理想树脂,并考察洗脱剂浓度对其解吸率的影响。结果表明,HPD400、HPD600、HPD720、HPD722树脂有较大的吸附容量和较高的解吸率,其中HPD722树脂显著优于另外3种,其最大吸附量为48.31 mg/g树脂,吸附平衡常数为0.619 1h-1,具有良好的静态动力学特性;用80%乙醇溶液洗脱吸附饱和的HPD722树脂,其解吸率可达89.59%。

| Abstract: | 18 macroporous resins were tested for their adsorption and desorption performance to resveratrol from polygonum cuspidatum sieb.et zucc,and 4 of them were selected for subsequent studies,which were carried out to investigate the static adsorption and desorption behaviors of the selected resins.It was indicated that four resins named HPD400,HPD600,HPD720 and HPD722 has the high adsorption and desorption rate,and HPD722 resin was more better than the others.It has higher adsorption capacity(48.31 mg/g) and la... |
