Description :
Prevention is better than cure. Instead of becoming, a victim of certain diseases due to consumption of polluted water. It is always advisable to drink purified water. Pollution of water due to the presence of certain heavy metal ions is a severe socio-environmental problems caused by the discharge of industrial wastewater. In this research paper, the adsorption ability of activated carbon derived from the bark of Ziziphus mauritiana for removal of cadmium from polluted water has been studied with respect to various parameters such as effect of pH, adsorbent dosage, contact time and initial cadmium concentration. The cadmium uptake was dependent on equilibrium pH=7.5, being the optimum pH values. The removal of cadmium from aqueous solution increases with increase in contact time and equilibrium was attained at 160 min. Further, on increasing adsorbent dose, there was increase of cadmium removal. The optimum adsorption (90%) was noticed at 6.0 g/l of adsorbent dose. The increase in initial concentration of cadmium led to decrease in the percent removal of Cd. This investigation verifies that the newly prepared activated carbon from the bark of Ziziphus mauritiana, can be used as a cost effective, valuable adsorbent for removal of Cadmium from aqueous solution and thus can be successfully applied for wastewater treatment.
