The present study deals with removal of Chromium(VI) from the synthetic sample using low cost physically and chemically activated carbon prepared from Casuarina Equestifolia fruit powder. The chemically(CaCl2 and MgCl2) activated carbon is prepared with Impregnation Ratio(I.R) of 0.75. A series of column tracer experiments have been performed with Chromium(VI) on the Physically and Chemically activated carbons for obtaining breakthrough and retardation coefficients. Adsorption capacities for physically, chemically activated CaCl2 and MgCl2 carbons are 0.341mg/g, 0.57mg/g and 0.416mg/g respectively.The values of Freundlich coefficient (KF), Freundlich Isotherm constant (1/n), Distribution Coefficient (KdF), Retardation Coefficient (R) for Physically activated carbon are 1.412,0.840,0.976,1.270 respectively and for CaCl2 activated carbon are 1.00,0.994,0.986,1.404 and for MgCl2 activated carbon 1.27,0.869,0.939 and 1.248 respectively.
