AB  - Dead biomass was treated with NaOH 0.1N for chromium removal from aqueous solution. MEB and FTIR analysis show that the dead biomass is clearly porous and contain complexing functional groups in their cellular wall. The adsorption isotherm and kinetics experiments of chromium onto dead biomass were then carried out to investigate the adsorption property. It shows that the adsorption capacity of chromium is about 65 mg g <SUP>1</SUP>. The adsorption isotherm was fitted by the Langmuir, Freundlich and Dubinin-Radushkevich (D-R), which reveals that the Langmuir model is the best one. Two kinetics models, pseudo-first-order and pseudo-second-order, were rearranged for expediently investigating the adsorption mechanisms. Fitting results show that the pseudo-second order is better in describing the adsorption process.
