Abstract: A metal-complexing template polymer was prepared in methanol solution by molecularly imprinted technique, using norfloxacin-zinc(II) complex as the template. The coordination mode between norfloxacin, zinc(II) and 4-vinylpyridine was studied by UV and IR measurements. The results show that the metal complexes are formed by the carboxyl, ketone groups of the norfloxacin and N of 4-vinylpyridine with Zinc(II). The prepared imprinted polymers display the obviously specificity adsorption for norfloxacin-zinc(II) complex, the specific adsorption capacity is 69.74 mol/g. The selectivity binding experiments indicate that the separation factor of the prepared polymers is 2.11 and 1.76 to Ketoprofen and (S)-ibuprofen, respectively.
