Agricultural wastes like tobacco stem, bulrush Scirpus acutits stem, Leucaena leucocephala shell, Ceibapentandra shell, Pongamia pinnata shell have been explored for the preparation of activated carbon. Characterization studies such as bulk density, moisture, ash, fixed carbon, matter soluble in water, matter soluble in acid, pH, decolourising power, phenol number, ion exchange capacity, iron content and surface area have been carried out to assess the suitability of these carbons as absorbents in water and wastewater. Adsorbents both organics and inorganics. The recovery of valuable adsorbents from readily and cheaply available agriculture wastes.
