摘要:
采用二步溶胀法制备了林可霉素分子印迹聚合物,并通过静态吸附实验,考察了其吸附等温线,吸附动力学特性和吸附扩散过程.对所得实验数据进行分析,同时,对分子印迹聚合物的吸附性能进行了评价.结果表明:分子印迹聚合物的吸附等温线可以用朗缪尔方程进行较好的拟合,相关系数可达0.995 6;分子印迹聚合物的吸附动力学过程可以用准二级模型进行很好的描述,其相关系数可达0.999 2.内扩散模型拟合结果为分段的直线,说明吸附过程受多种作用力的影响. 林可霉素分子印迹聚合物吸附容量较高,可达83.08 mg/g;结合过程很快,在非极性环境中80 min可达吸附平衡.制备的分子印迹聚合物是一种性能优良的新型吸附剂,可以成功地应用于吸附分离液体中的林可霉素.
Abstract:
Lincomycin molecular imprinted polymer was prepared by two-step swelling polymerization. The adsorption isothermal, adsorption kinetics and the diffusion process of molecularly imprinted polymer were investigated, and the adsorption properties of imprinted polymer were discussed by analyzing experiment data. The results show that the adsorption isothermal and the kinetics of imprinted ploymer are well fitted by Langmuir model and pseudo-second-order equation, whose regression coefficients are 0.995 6 and 0.999 2, respectively. The fitting result of internal diffusion model shows a segmented straight line, which indicates that the adsorption process is affected by a variety of forces. Lincomycin molecularly imprinted polymer has good adsorption capacity of 83.08 mg/g and rapid adsorption equilibrium within 80 min in non-polarity environment. The prepared molecularly imprinted polymer can be successfully applied to the separation of lincomycin in solution, as a new adsorption material with excellent performance.
