乙二醇

Molecularly imprinted polymers of sulfamethazine(SM 2 ) were prepared with silica gel as a sacrificial material, methacrylic acid and 4 vinylpyridine(4 Vp) as functional monomers, glycol dimethacrylate as crosslinker. The polymer properties were investigated by static adsorption experiments. Scatchard analysis shows that the adsorption ability of MAA MIP is superior to that of 4 Vp MIP. The dissociation constant of MAA MIP is 9 59×10 -4 mol/L. The value of apparent binding a...

以磺胺二甲嘧啶为模板分子，分别用甲基丙烯酸和4乙烯基吡啶为功能单体，二甲基丙烯酸乙二醇酯为交联剂，采用牺牲硅胶法合成了磺胺分子印迹聚合物，通过静态吸附实验，系统研究了不同单体对聚合物识别性能的影响；Scatchard分析表明，以甲基丙烯酸为单体的聚合物具有较高的吸附能力，其离解常数Kd为959×10-4mol/L，最大表观结合位点数Qmax为3070μmol/g。
