ADSORPTION OF CR-(VI) FROM AQUEOUS ENVIRONMENT USING NEEM LEAVES POWDER

Abstract

This study is aimed at utilizing Neem Leaves powder as low cost adsorbent material for removal of Cr-(VI) from aqueous solution. Adsorption is an important process used for removal of colour, odour, turbidity, metal ions and reduction of COD. In adsorption, the solute present in dilute concentration in liquid or gas phase is extracted by contacting with suitable solid adsorbent so that the transfer of the component first takes place on the surface of solid and then into the pore of the solid. Neem Leaves powder Adsorbent used in present study is prepared at Laboratory scale which is very effective to remove chromium from its aqueous solution. This study describes the detailed experimental procedure to obtain Adsorption Equilibrium and the Effect of various parameters such pH, agitation time, initial metal ion concentration & adsorbent doses on batch technique.
