Abstract

A novel activated carbon produced from cherry laurel (Laurocerasus officinalisRoem.) seeds (CLSAC) by chemical activation with ZnCl2 was used as an adsorbent to remove Cr(VI) ions from aqueous solutions. CLSAC was characterized by several techniques and the adsorption experiments were performed in a batch model adsorption technique. The effects of various experimental parameters were investigated as a function of solution pH, contact time, initial Cr(VI) concentration, CLSAC concentration, and temperature. The monolayer adsorption capacity of CLSAC was found to be 41.67 mg g(-1) for 5.0 g L-1 of CLSAC concentration and, it was concluded that CLSAC can be used as an effective adsorbent for removal of Cr(VI) from waters and wastewaters.
