Water depollution via adsorption is an energy-efficient technique that uses activated carbon produced from walnut shells to remove different pollutants. Our research integrates theoretical and experimental approaches comprehensively understand the subject. By analyzing organic functional groups in shell-derived (AC-Ws), evaluating performance, employing DFT analysis, optimizing conditions, we provide valuable insights into application of AC-Ws for removing pesticide pollutants wastewater. The properties this (AC-Ws) are identified by techniques such as XRD, FTIR, SEM/EDX, pHzpc, Boehm titration. A response surface methodology (RSM) has been utilized develop experiment aqueous solutions two herbicides, 2,4,5-trichlorophenoxyacetic acid (2.4.5-T), 2,4-Dichlorophenoxyacetic (2,4-D). Abbreviations technical terms will be explained when first used, objective language used throughout. Grammar spelling conform British standards. examined removal herbicides based on three independent variables; pH, dosage, temperature, within specific ranges (pH: 4–10, dosage: 0.1–0.3 g/L, temperature: 20–40 °C). conducted 17 experiments using Design-Expert software. Optimal conditions included pH 4 dosage 0.3 g/L 2.4.5-T 5 0.1 2,4-D. These demonstrated efficiency 98% desirability function 1.000 92% findings suggest process was thermodynamically favorable exothermic. data described accurately pseudo-second order kinetic model, Freundlich isotherm model showed good alignment with equilibrium data. Using method, functions were adsorbent's surface, density theory (DFT) applied evaluate mechanism sites.
