Industrial wastewater treatment is essential to mitigate pollution and address global water scarcity. In this study, an activated carbon/copper (II) complex (AC/CuL) composite was obtained for enhanced removal of organic compounds by coupling adsorption oxidation. Tests were performed using Drimaren Red X-6BN (DRX-6BN) oily effluent at pH~6.0. obtain the kinetics DRX-6BN (20 mg/L) 25 °C amount 0.42 g/200 mL solution. The data well fitted several models, suggesting a process; however, best fit achieved pseudo-second-order (PSO) model (R2 = 0.9996). Freundlich model. addition hydrogen peroxide system reduced need adsorbent, removing approximately 100% chemical oxygen demand (COD) from emulsion in 120 min only 0.04 g AC/CuL. material exhibited high storage stability maintained its effectiveness oil grease (O&G) content COD least 12 months. These results indicate that AC/CuL promising compounds, such as textile petroleum industries. findings offer sustainable, economical, safe approach treatment.
