摘要:
采用沉淀聚合法,以磺胺二甲基嘧啶(sulfadimidine,SM2)为模板分子,甲基丙烯酸为单体,乙二醇二甲基丙烯酸酯为交联剂,制备一种SM2的分子印迹聚合物。对其形态进行表征,并对其吸附性能、选择性等进行了研究。结果表明:分子印迹聚合物微球呈不规则球形,平均粒径为368 nm;在一定浓度范围内,聚合物的吸附量Q与吸附液质量浓度C有一定的线性关系,线性方程是Q=0.145 1 C+0.227 1,R2=0.997 9。可见,聚合物对SM2有良好的选择性和重复利用性,可作为一种SM2的富集材料。
Abstract:
A molecular imprinted polymer was prepared by precipitation polymerization with sulfadimidine as template molecule,methacylate as monomer and ethylene glycol dimethacrylate as crosslinking agent.Its morphology,adsorption and selectivity were studied.The results showed that the molecular imprinted polymer microspheres were spherical with an average particle size of 368 nm.Within a certain concentration range,the adsorption capacity of the polymer Q had a certain linear relationship with the concentration of the adsorption solution C of sulfadimidine.The linear equation was fitted as Q=0.145 1 C+0.227 1,R2=0.997 9.The polymer showed good selectivity and reusability for sulfadimidine and could be used as a kind of enrichment material for sulfadimidine.
