以氨基脲(SEM)为模板分子,α-甲基丙烯酸(MAA)为功能单体,乙二醇二甲基丙烯酸酯(EDMA)为交联剂,采用本体聚合方式在不同溶剂中合成一系列分子印迹聚合物(MIP)。通过静态吸附实验,研究聚合体系组成对氨基脲MIP吸附性能的影响,并进行Scatchard分析。结果表明,模板分子与功能单体为1∶4,以V(甲醇)∶V(乙腈)=1∶1作溶剂合成的MIP对模板分子的结合性最佳,且通过氢键作用形成一类等价的结合位点,其结合位点的离解常数KD=1.44 mmol/L。 Using semicarbazide (SEM) as the template molecule, α-methacrylic acid (MAA) as the functional monomer and ethylene glycol dimethacrylate (EDMA) as the crosslinking agent, bulk polymerization was used to synthesize a series of Molecularly Imprinted Polymer (MIP). The static adsorption experiment was conducted to study the influence of the polymerization system composition on the MIP adsorption of semicarbazone, and the Scatchard analysis was carried out. The results showed that the MIPs with template and functional monomers of 1: 4 and synthesized with V (methanol): V (acetonitrile) = 1: 1 as solvent showed the best binding to template molecules and formed a kind of hydrogen bonding The equivalent binding site, the binding site dissociation constant KD = 1.44 mmol / L.
