用于检测莱克多巴胺的磁性分子印迹聚离子液体及其制备方法和用途

Abstract

本发明公开了用于检测莱克多巴胺的磁性分子印迹聚离子液体及其制备方法和用途,它是由载体、功能单体、交联剂、模板分子在引发剂作用下聚合后洗脱模板分子制成的颗粒状材料,所述功能单体为1-乙烯基-3-乙基咪唑六氟磷酸盐,所述交联剂为溴化1,4-丁烷-3,3’-双-1-乙烯基咪唑,所述模板分子为莱克多巴胺。本发明磁性分子印迹聚离子液体以离子液体1-乙烯基-3-乙基咪唑六氟磷酸盐为功能单体,以离子液体交联剂溴化1,4-丁烷-3,3’-双-1-乙烯基咪唑为交联剂聚合而成,实验表明它对莱克多巴胺能快速达到吸附平衡状态,同时具有较高的吸附容量和良好的选择吸附能力,最大吸附量为20.50μmol/g。
The invention discloses magnetic molecular imprinting polyion liquid for detecting ractopamine as well as a preparation method and an application of the magnetic molecular imprinting polyion liquid. The magnetic molecular imprinting polyion liquid is a granule material prepared in steps of polymerizing a carrier, a function monomer, a crosslinking agent and template molecules in the presence of an initiating agent and then eluting the template molecules, wherein the functional molecule is 1-ethyl-3-ethylimidazole hexafluorophosphate, the crosslinking agent is bromination 1,4-butane-3,3'-bis-1-vinyl imidazole, and the template molecule is ractopamine. According to the magnetic molecular imprinting polyion liquid, the ion liquid 1-ethyl-3-ethylimidazole hexafluorophosphate is adopted as the functional monomer, the ion liquid cross-linking agent is adopted as a cross-linking agent, the experiment shows that the magnetic molecular imprinting polyion liquid can rapidly reach an absorption balance state for the ractopamine and is high in adsorption capacity and good in selective adsorption capacity, and the maximum adsorption amount is 20.50 mu mol/g.
