摘要
通过比较8种大孔吸附树脂对烟草绿原酸的吸附分离性能,筛选出适合分离烟草绿原酸的树脂,并对其动态吸附特性进行研究。结果表明,XDA-1树脂对烟草绿原酸不仅吸附量大,而且解吸率高,适合烟草绿原酸的分离富集。该树脂吸附分离烟草绿原酸的工艺参数为:上柱液浓度3.5mg/mL,pH3.0,流速3倍柱床体积/h;以6倍柱床体积的40%乙醇进行洗脱,解吸附效果最佳,绿原酸总回收率为80.06%,初步吸附分离得到的产品中绿原酸含量为39.20g/100g。
Eight types of macroporous resins were selected for adsorption and separation of tobacco chlorogenic acid.It was found that resin XDA-1 was an excellent adsorbent with higher adsorption and desorption capacity.The effects of concentration,pH and flow rate of the solution on the dynamic adsorption of resin XDA-1 were also studied.The results showed that the optimal adsorption conditions are as following: chlorogenic acid concentration of extract solution at 3.5 mg/mL,pH 3.0,flow rate at 3 BV/h.Using 6 BV 40%...
