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


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.
