THE ADSORPTION OF CHLORPYRIFOS AND MALATHION UNDER ENVIRONMENTALLY RELEVANT CONDITIONS USING BIOWASTE CARBON MATERIALS

Water bodies face persistent contamination from organophosphorus pesticides like chlorpyrifos and malathion, which pose substantial environmental and health hazards due to their toxicity and resilience in ecosystems. This study explores the potential of spent coffee grounds, a common agricultural byproduct, as an eco-friendly adsorbent for eliminating these pesticides from polluted water. Spent coffee grounds underwent carbonization at 400 °C and various activation treatments using KOH, H
