The natural plant based adsorbent (Tea powder) was activated by heating and treating it with 2N HCl and dried at 150oC for 2 hrs, stored and used for adsorption studies. The Groundnut oil, Coconut oil, Gingelly oils and Hydrocarbons like Hexane, Benzene, Kerosene, Petroleum ether and Toluene were selected for adsorption studies. The pH and heat had no effects on oil as it is inert to the same, at room temperature. The contact time and dose had effect on the adsorption which increases the adsorption with increase in the time and dose. The XRD spectral study of adsorbent before and after adsorption, confirms the adsorption process. The percentage of adsorption was calculated using spectrophotometry.
