Abstract
Guar derived chelating ion-exchange resin, functionlized with 5-bromo anthranilic acid (GTBAA), was synthesized by the reaction of 5-bromo anthranilic acid with the guar triazine. The resin characterization viz., bulk density, moisture content, specific bulk volume, degree of substitution, IR spectra, nitrogen content, pH titration and ion-exchange capacity was determined. Metal analysis was done by using atomic absorption spectrophotometry. The effect of pH was considered in a batch equilibrium study on the chelation of Co(II), Ni(II), Cu(II), Zn(II), Cd(II) and Mn(II) metal ions. The metal capacity of resin at different pH was evaluated. The quantitative separation of copper and manganese was achieved using column separation through batch equilibrium method. At the maximum pH of adsorption, the resin capacity follows the order : Cu(II) > Zn(II) > Co(II) > Ni(II) > Mn(II) > Cd(II).
