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...
