文摘

Utilization of modified Litchi peel (MLP) as a cheap and effective sorbent for the removal of Cr(VI). The adsorption process on Cr(VI) increased in 80 min and almost reached adsorption equilibrium. The adsorption amount at equilibrium increased with the increase of temperature. The biosorption was endothermic. The pseudo-second-order equation fitted the experimental data very well.
