本文通过对吸附率及解吸率的测定,确定最佳型号树脂、静态和动态吸附及解吸的相关影响因素。结果表明:DM-130型大孔树脂最佳,其最佳动态吸附条件为:pH值5.8(原液pH值)、上柱浓度1.0mg/mL、上柱流速4.5mL/min,此时吸附率达88.9%;最佳解吸条件为:解吸液80%乙醇、解吸流速2.0mL/min,此时解吸率为93.5%,所得物质黄酮纯度为78.64%,较原来的15.42%提高了5.1倍。
In this paper, the determination of adsorption rate and desorption rate, to determine the best model resin, static and dynamic adsorption and desorption related factors. The results showed that the best dynamic adsorption conditions for DM-130 macroporous resin were as follows: pH value of 5.8 (pH value of the original solution), concentration of 1.0mg / mL on the column and flow rate of 4.5mL / min on the column. The adsorption rate Up to 88.9%. The best desorption conditions were: desorption solution 80% ethanol, desorption flow rate 2.0mL / min, the desorption rate was 93.5%, the purity of flavonoids was 78.64%, 5.1 times higher than the original 15.42%.
