Abstract

Conditions of the synthesis of nanoparticles of ractopamine molecularly imprinted polymers (MIP) by the precipitation method are studied. It is shown that the size and dispersity of MIP particles are largely determined by the nature of the functional and cross-monomers and by the synthesis conditions: temperature, mixing rate, duration of synthesis, and ultrasonic treatment of the polymerization mixture before and after the synthesis. It is found that ractopamine MIP particles based on methacrylic acid and ethylene glycol dimethacrylate, sonicated for 30 min, have a minimum size and degree of dispersion. Using the piezoelectric quartz micro-weighing method, characteristics of the recognition layer based on MIP nanoparticles are found, and the analytical characteristics of a sensor for the determination of ractopamine in an aqueous solution are calculated.

基于莱克多巴胺分子印迹聚合物的纳米粒子的压电传感器

摘要

瑞克托帕明分子印迹聚合物的纳米颗粒的合成的条件下(MIP)通过沉淀法进行了研究。结果表明,MIP颗粒的大小和分散度在很大程度上取决于官能团和交叉单体的性质以及合成条件:温度,混合速率,合成持续时间以及在聚合反应前后的超声处理。合成。已发现,超声处理30分钟的基于甲基丙烯酸和乙二醇二甲基丙烯酸酯的莱克多巴胺MIP颗粒具有最小的尺寸和分散度。使用压电石英微称量法,发现了基于MIP纳米颗粒的识别层的特性,并计算了用于测定水溶液中莱克多巴胺的传感器的分析特性。
