This study investigates the adsorption of two model pesticides, 2,4-dichlorophenoxyacetic acid (2,4-D) and carbofuran, on activated carbons derived from peach stones through chemical activation with phosphoric acid. The optimal synthesis conditions were identified as an impregnation time of 5 hours, an impregnation ratio of 3.5, an activation temperature of 400°C, and an activation time of 4.5 hours, resulting in a specific surface area of 1182 m²/g. The activated carbon's surface chemistry was characterized using pH at the point of zero charge, scanning electron microscopy, and Fourier transform infrared spectroscopy. Kinetic and equilibrium adsorption tests were conducted, revealing that 2,4-D adsorption follows a pseudo first-order model, while carbofuran adsorption follows a pseudo second-order model. The equilibrium adsorption capacity for 2,4-D was higher than that for carbofuran ( approximately 500 and 250 mg/g, respectively). Thermodynamic analysis suggested that the adsorption process is predominantly physisorption. The study highlights the potential of these activated carbons for the removal of pesticides from water.This study investigates the adsorption of two model pesticides, 2,4-dichlorophenoxyacetic acid (2,4-D) and carbofuran, on activated carbons derived from peach stones through chemical activation with phosphoric acid.
