Abstract: A new Hg(II) ion-imprinted polymer(Hg(II)-IIP) microspheres was synthesised for the separation and recovery of Hg(II) ion from water sample. Hg(II)-IIP was prepared by copolymerisation of 2-allylsulfanyl-5-(4-pyridinyl)-[1,3,4]thiadiazole(AST), phenylethylene(St) and Hg(II) ion. The structure and morphology of Hg(II)-IIP and NIP were characterized by Fourier transform infrared spectroscopy(FT-IR) and scanning electronmicroscopy(SEM). The adsorptive properties and the selectivity recognition ability of Hg(II)-IIP were investigated. The results indicated that the maximum adsorption capacity was 38.5mg/g, the adsorption capacity reached equilibrium need 30 min at pH 5-8. Using 0.1mol/L HCl and 0.5 mol/L thiourea as desorption solvent, the desorption rate was more than 97%. The relatively selective factor (αr) values of Hg(II)/Cd(II), Hg(II)/Co(II), Hg(II)/Ni(II), Hg(II)/Zn(II)and Hg(II)/Mn(II)are 6.56, 14.9, 14.5, 8.53 and 12.1, respectively. Hg(II)-IIP had excellent adsorption and selective recognition properties.
