摘要:
选择6种大孔吸附树脂, 比较其对油茶叶黄酮(FCOA)的吸附量和解吸率, 筛选出较优的油茶叶黄酮吸附剂, 并对其静态吸附动力学曲线和动态吸附性能进行了考察. 实验结果表明, D101树脂适合于FCOA的吸附分离, 其吸附机理符合Langmuir单分子层吸附. D101树脂吸附分离FCOA适宜的工艺参数为: 上样液浓度为1.2mg/mL左右, pH值3.29, 上样流速 2BV/h, 溶液处理量为19BV; 洗脱剂为70%乙醇, 洗脱流速2BV/h, 洗脱剂用量约4BV
摘要(英文):
Adsorption quantities and desorption rates of six types of macroporous resins for adsorption/desorption of flavonoids from Camellia oleifera Abel leaves (FCOA) were compared to pick out adsorption resins with higher adsorption performances. Static adsorption kinetic curves and dynamic adsorption properties were also investigated. The experimental results showed that D101 macroporous resin was the most suitable resin to adsorb/desorb FCOA with its adsorption mechanism conforming to Langmuir-single-molecule-layer theory. The practicable technical parameters for adsorption/desorption of FCOA by D...
