Abstract

A molecular imprinted polymer for Hg(II) has been fabricated using free radical polymerization method. The selectivity and binding capability of the fabricated molecular imprinted polymer towards Hg(II) ions in aqueous environment has been carried out. Molecular imprinted polymer was prepared using mercury(II) nitrate dihydrate as the template molecule and vinylcarbazole as the functional monomer. Free template polymer was then used in metal uptake study at different pH, timing and equilibrium concentration. The molecular imprinted polymer shows highest adsorption at pH 6 for 135 min at 40 ppm Hg²⁺ solution. The kinetic order of the adsorption is second order with equilibrium rate constant 9.0 × 10^-4 min ppm^-1. The adsorption obeys the Langmuir isotherm with maximum adsorption of 10.13 mg g^-1 and Langmuir constant 0.032 gm g^-1. In selectivity study, the distribution coefficient of Hg²⁺ is much higher than Cd²⁺ and Zn²⁺ that is 10443.31, 73.74 and 28.66, respectively.
