中文摘要:
      以结晶紫(CV)为模板分子,α-甲基丙烯酸(MAA)为功能单体,二甲基丙烯酸乙二醇酯(EGDMA)为交联剂,采用沉淀聚合法合成结晶紫分子印迹微球。同时考察合成过程中不同交联剂、模板分子与交联剂的配比以及交联剂的用量对微球性能的影响。结果表明:采用恒温水浴振荡法,30 mL乙腈为交联剂,模板分子、功能单体和交联剂摩尔比为1 : 4 : 20,所制备合成的聚合物微球最大吸附量Q为39.1 μmol/g,分离因子α和印迹效率因子β分别为3.76和3.18,对目标分子结晶紫具有良好的特异性识别和吸附能力。
英文摘要:
      The molecularly imprinted microspheres for crystal violet (CV) were synthesized by precipitation polymerization in which crystal violet was used as template, α-methacrylic acid (MAA) as functional monomer and ethylene glycol dimeth acrylate (EGDMA) as crosslinker. Meanwhile, the properties of microspheres for different crosslinkers and dosage, different mole ratio of functional monomers to templates were also investigated. The optimal conditions were as follows: shaking bath, 30 mL acetonitrile as solvents, EGDMA as cross-linker and the molar ratio of CV : MMA : EGDMA= 1 : 4 : 20. Under this synthesis conditions, the adsorption capacity of polymer microspheres were as high as 39.1 μmol/g,separation factor α and imprinting efficiency factor β are 3.76 and 3.18 respectively. It showed good identification and adsorption ability to target molecules.
