Abstract

A synthesis method of granulated polymeric sorbents based on 2-hydroxyethylmethacrylate and ethylene glycol dimethacrylate that possess affinity to glucose sorption sites formed by boric acid molecules has been developed. The participation of boric acid as an additional crosslinking agent and the effect of the amount of the introduced ligand on the surface morphology of the granules and physicochemical properties of the polymeric sorbents have been determined. It has been found that this modification of the polymer matrix promotes an increase in the affinity of the sorption surface and its adsorption capacity to bind glucose in a dynamic mode, as well as high selectivity in comparison with the sorption of its structural analogue, fructose. This can further be used in the development of a method of isolation of glucose from a multicomponent solution and a sorption method of separation of sugars.

基于硼酸修饰的2-甲基丙烯酸羟乙酯和乙二醇二甲基丙烯酸酯作为葡萄糖高亲和力配体的选择性吸附剂

研究了以2-羟乙基甲基丙烯酸酯和乙二醇二甲基丙烯酸酯为基础，对硼酸分子形成的葡萄糖吸附位点具有亲和力的颗粒状高分子吸附剂的合成方法。测定了硼酸作为附加交联剂的参与以及引入配体的量对颗粒表面形貌和高分子吸附剂理化性能的影响。研究发现，聚合物基质的这种修饰促进了吸附表面亲和力的增加，以及其以动态模式结合葡萄糖的吸附能力，与其结构类似物果糖的吸附相比，具有很高的选择性。这可进一步用于开发从多组分溶液中分离葡萄糖的方法和分离糖的吸附方法。
