The effective removal of heavy metals from industrial wastewater is among the most important issues for many industrialized countries. Removal of cadmium(II) from aqueous solutions was studied using activated carbon made from stems of Salvadora persica. Batch adsorption experiments were performed as a function of pH, contact time, solute concentration and adsorbent dose. The optimum pH required for maximum adsorption was found to be 5 for cadmium. The maximum contact time for the equilibrium condition is 180 min at the sorbent dose rate of 2.5 g. The maximum efficiency of cadmium removal by activated carbon was found to be 81.7%. The results were well fitted with both Langmuir and Freundlich isotherm models. [ABSTRACT FROM AUTHOR] |
