Abstract: The pesticide industry discharges a lot of waste water that causes a lot of environmental and health problems. In the present study, Adsorption has been proved to be an effective mechanism for the removal of pesticide from synthetic waste water using bagasse fly ash and rice husk ash as a low cost adsorbent. Several operating parameters: contact time (t), initial pH, adsorbent dose and concentration of pesticide were studied for their effect on removal efficiency. It has been seen that pH of the solution greatly influences the removal when it is acidic in nature. The removal efficiency for BFA and RHA is 90% and 86% respectively. The optimum pH of the solution was found to be 4, adsorbent dose is 20g/l, contact time (180 min) both for BFA and RHA. The waste produced during the process was analyzed. SEM, TGA and XRD were done to determine the major compounds in waste and to see their burning characteristics. In this way Adsorption is a good technique for the removal of pesticides.
