Abstract: The molecular imprinted polymer was synthesized by precipitation polymerization with cadmium(Ⅱ)- glyoxalbis(2- hydroxyanil) as template,methacrylic acid as functional monomer and ethylene glycol dimethacrylate as cross- linker.The imprinted polymer adsorption and selective recognition to the template molecule and the effects of acidity were studied,and the optimal adsorption conditions,factors such as concentration,temperature and time were investigated by flame atomic absorption spectrometry.The results show that imprinted polymer has a good adsorption and selection by template molecule,the adsorption equilibrium could be reached in 45 mins.
