Abstract

Attempt has been made to develop methodologies for preconcentration of chromium in the biodegradable polymer beads. The uptake behaviors for chromium have been studied with Ca-alginate (CA) and Fe-doped calcium alginate (Fe-CA) beads. The work also aims to study the differential attitude of CA and Fe-CA towards Cr(III) and Cr(VI) so that, depending on the oxidation state of chromium effluent, environmentally sustainable methodologies can be prescribed for removal of chromium. Radiotracer ⁵¹Cr has been chosen as precursor of stable chromium throughout the experiment. It was found that Fe-CA beads are suitable for removal of Cr(III) and Cr(VI) while CA beads can be used for the speciation and separation of Cr(III) and Cr(VI) at pH 5.
