摘要：
Adsorption 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. Adsorption equilibrium experiments were carried out at different pH. The equilibrium data were correlated with the Langmuir, Freundlich and Sips equations. The internal diffusion coefficients were determined by comparing the experimental concentration curves with those predicted from the surface diffusion model and the pore diffusion model.
