Abstract: The purpose of this study is to prepare a new ion imprinted polymer for Mo (VI) with high selectivity. Ion-imprinted polymer (IIP) particles were synthesized by thermally copolymerization. For the synthesis of the ion imprinted polymer, the ion pair of [Mo(VI)-thiocyanate] and NR4+ was used. The ion pair was precipitated in an aqueous phase and then dissolved in acetonitrile as a porogen. The imprinted ion was removed using 10% (v/v) methanol in HCl (0.5 mol L-1). The unleached and leached IIP particles were characterized by infrared spectroscopy, thermogravimetric analysis, surface area analysis, scanning electron microscopy and energy dispersive X-ray analysis. The use of the new Mo(VI)-IIP in solid phase extraction revealed a maximum adsorption capacity of 3.77mg Mo(VI) per gram of Mo(VI)-IIP in optimum conditions of extraction. The selectivity coefficients of the IIP for Mo in comparison with other metal ions were also evaluated. The proposed Mo-IIP was successfully applied for Mo(VI) determination in different types of water samples.
