An Experimental Investigation on Biosorption of Cadmium by Erythrina Variegate Orientalies as an Adsorbent

Nageswara Rao.L, P.Rohini Kumar and D.Kamalakar

An unauthorized activity of releasing harmful contaminants arising from domestic, municipal and industrial establishments into the environment is continuing unabated due to expensive treatment process and ineffective implementation of environmental legislation. In developing countries with the result there is a study increase in concentrations of pollutants sometimes reaching alarming levels and causing serious human health hazards of the life, sustaining water resource due to release of industrial effluents is one of the serious environmental problems encounter today. In the present work an attempt is made to study to effect of parameters like pH, temperature, time of contact, bisorbent dosage, size of bisorbent etc. on removal of Cadmium and determination of equilibrium, kinetics and thermodynamic parameters in a batch biosorption of cadmium by the leaf powder of Erythria Variegate Orientalies as biosorbent.
