| 摘 要： | 研究了6种吸附树脂对香兰素的吸附和解吸附能力，筛选出最佳树脂SepabeadsSLY207，确定了Sepabeads SP207树脂的最佳吸附与解吸附工艺参数：吸附：pH=6，室温，流速1．5BV／h，溶液处理量为7BV；解吸：洗脱剂为无水乙醇溶液，流速1BV／h，洗脱剂用量4．5BV。在最佳条件下，对香兰素的吸附率为85，5％，解吸率为89．8％。

| Abstract: | The adsorption and desorption ability of 6 adsorbing resins to vanillin were studied.The Sepabeads SP207 resin was the best of the 6,and the optimal technics parameters for adsorption and desorption were determined as follows: adsorption: pH=6,room temperature,flow velocity of 1.5 BV/h,the adsorption volume 7 BV;desorption: being washed with anhydrous ethanol at the flow velocity of 1 BV/h,the volume of anhydrous ethanol 4.5 BV.The adsorption rate and desorption rate to vanillin were 85.5% and 89.8% respectively under the optimal condition. |
