In this study Agriculture waste (Rice husk) and timber industry waste (Saw dust) were selected for the making of adsorbent. Because of their easily availability, low cost, easy preparation, handing and storage make them suitable low cost biosorbents. The removal of three metal pollutants commonly encountered in electroplating effluents namely- Chromium, Nickel and Copper has been investigated. The objectives of this study were: 1. Preparation and characterization of biosorbents using rice husk and saw dust. 2. To explore the adsorption efficiency of different biosorbents under different experimental conditions including pH, biosorbents dose, initial metal ion concentration, contact time and temperature in batch mode experiments and in mono, binary and multi-metal systems. 3. Application of different isotherms to the generated data. 4. Desorption studies to explore the reuseability of the biosorbents. 5. Removal of heavy metals from industrial effluent under optimum experimental conditions.
