Removal of chromium ions from aqueous solution by composite alginate beads

摘要：

In this study, the removal of hexavalent and trivalent chromium ions from aqueous solution by various composite alginate beads was investigated in a batch reactor. Ca-alginate beads, protonated beads, and dithionite entrapped beads were prepared and used for the experiment. Equilibrium sorption experiments were carried out at different pH and temperature. The equilibrium data were correlated with Langmuir and Freundlich equations. The influence of initial chromium concentration and sorbent concentration on the adsorption kinetics was studied.
