Abstract

An investigation is performed for isotherms of the equilibrium sorption of glucose by surface-imprinted organic-inorganic sorbents based on 2-hydroxyethyl methacrylate and ethylene glycol dimethacrylate. It is shown that modifying the copolymer by forming imprint sites reduces the affinity of the sorption surfaces and the monolayer sorption of glucose molecules. In analyzing the match between experimental data obtained under conditions of sorption corresponding to those for the formation of imprint sites and theoretical models of sorption, it is found that introducing 6 mol % glucose molecules as a template produces homogeneous sorption surfaces. The surfaces of organo–inorganic sorbents available for the target sorbent in a liquid–solid system are determined using the Giles classification of experimental sorption isotherms and theoretical models of sorption isotherms.

表面印迹有机-无机吸附剂对葡萄糖的平衡吸附

摘要

对基于 2-羟乙基甲基丙烯酸酯和乙二醇二甲基丙烯酸酯的表面印迹有机-无机吸附剂对葡萄糖平衡吸附的等温线进行了研究。结果表明，通过形成印迹位点对共聚物进行改性会降低吸附表面的亲和力和葡萄糖分子的单层吸附。在分析在对应于印记位点形成的吸附条件下获得的实验数据与吸附理论模型之间的匹配时，发现引入 6 mol% 葡萄糖分子作为模板会产生均匀的吸附表面。
