Abstract: An increase in population causing rapid industrialization was found to consequently increase the generation of wastewater. Heavy metals are the major toxicants found in industrial wastewaters. Conventional methods for the removal of metal ions such as chemical precipitation and membrane filtration are exceptionally expensive. Biosorption and bioaccumulation are eco-friendly alternatives for bioadsorption process. An Orange, Mosambi, Lemon and Banana peel, a discarded organic waste which is used to produce bioadsorbent. The orange and lemon peel based bioadsorbent was assessed for removal of heavy metal pollutant. Fly Ash, a waste of the Raichur Thermal Power Plants has been utilized as an adsorbate. The various experimental conditions such as pH, particle sizes, adsorbent dosage and variation of temperature which effects the heavy metal pollutant adsorption were investigated for orange and lemon peel. The percentage of adsorption was found to be more for orange & lemon peel. The maximum adsorption capacity of orange and lemon peel was observed at pH4 of about 53% and 31% respectively, 30°C of temperature of about 37% and 21% respectively, 100 µ of particle size 100 of about 81% and 82% respectively and 1gm of adsorbent dosage of about 21% and 22% respectively.
