Abstract: A macroreticular polystyrene based chelating ion exchanger containing nitrosocatechol as the functional group has been synthesized. The resin is found to be stable in acidic as well as in basic media. Physicochemical properties of the resin are examined. Sorption capacities of the heavy metal ions on resin are found to be quantitative in the pH range of 1.0 – 7.0. Sorption kinetics of metal ions on the resin is studied. The total sorption capacities of the metal ions as a function of pH were 0.35 mmol/g at pH 4.0, 0.19 mmol/g at pH 5.0 and 0.06 mmol/g at pH 6.0 for Cd(II), Hg(II) and Pb(II) ions, respectively. Under competitive conditions the system shows higher selectivity of Cd(II). The sorption and desorption characteristics for cadmium(II), lead(II) and mercury(II) are studied with a view to utilizing the resin for the removal of cadmium(II), lead(II) and mercury(II) as well as preconcentration of cadmium(II) ions from water samples by column operation.
