摘要：

The removal of chromium (III), copper (II) and zinc (II) from aqueous solution by adsorption on carrot residues (CR) was studied. Biosorption of chromium (III), copper (II) and zinc (II) on CR were compared. It was shown that CR has high metal removal efficiency. The Freundlich and Langmuir model can describe the adsorption equilibrium of chromium (III), copper (II) and zinc (II) on CR. The Freundlich and Langmuir constants for biosorption of chromium (III), copper (II) and zinc (II) on CR were determined. The effect of solution pH on biosorption was studied. (C) 2004 Elsevier Ltd.
