Removal of Cr (VI) From Aqueous Solution Using Camellia Oleifera Abel Shells

摘要

The use of camellia oleifera abel shells as biosorbent has been successfully demonstrated in the removal of Cr (VI) from aqueous solution.The effects of different parameters,such as,contact time,initial concentration of Cr (VI),pH and temperature on Cr (VI) adsorption were investigated.The results showed that the maximum uptake of Cr (VI) was up to 190.69 mg/g at a pH value of around 1.0,under the initial Cr (VI) concentration of 400mg/L and at the temperature of 298 K.The adsorption kinetics could be described by pseudo-first order and pseudo-second order kinetics models.
