Abstract

Aluminium extraction was studied by means of ion selective chelating ion exchange resin synthesized form cross linked chitosan functionalized with iminodiaceticacid dihydroximate. The separation is carried out by column chromatography. IR spectra, nitrogen content (calculated by Kjeldahl method) and pH titration (using batch method) were made for resin characterization. Resin characteristics such as moisture content, bulk density, specific bulk volume and ion exchange capacity were also determined by standard methods. Metal uptake analysis was done by batch method using atomic absorption spectrophotometer. The distribution coefficient values at different pH levels were determined from batch method. Estimation of Al (III) was done by U.V. Spectrophotometer at 535nm. Aluminium showed maximum Dg value at pH 2.0.

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).
