【 摘 要 】

Pesticides are frequently used in agriculture, which contaminates both surface and ground water. Surface adsorption, photocatalysis, membrane separation and biodegradation are methods to remove the pesticides. These methods are expensive and time consuming. In this study silver nanoparticles were synthesized by using endophytic bacterial strain VXB8. A nanocomposite (CAB with 20 mg silver nanoparticles) has been designed for the removal of organophosphate compounds from aqueous solution. Individually after passing 100 μg/mL of chlorpyrifos, malathion, dichlorvos and profenofos solution through nanocomposite, the removal efficiency of pesticides has been analyzed by UV/Visible spectroscopy and GC-MS analysis. The removal efficiency of chlorpyrifos, malathion, dichlorvos and profenofos is 88.49, 75.79, 78.2 and 64.1 % respectively. The proposed method is simple, rapid, environmentally friendly with good pesticides removal efficiency.
