Contaminants of emerging concern (CECs) in water, including pharmaceuticals and personal care products, represent a significant threat to environmental human health. In this context, the electro-Fenton (EF) process has emerged as highly effective technique for removal such pollutants. This study investigates innovative use tea waste material (TWM) combination with copper-iron nanoparticles (FeCuNPs) degrade mixture CECs. A central aspect research is sustainable reuse organic material, TWM, support catalytic nanoparticles. approach not only utilizes resource that would otherwise be discarded but also promotes sustainability treatment contaminated aligning principles circular economy. The as-prepared FeCuNPs@TWM catalyst was fully characterized, critical parameters influencing pollutant were assessed, adsorption capacity, load, applied current. Under optimized conditions, EF process, enhanced by FeCuNPs@TWM, achieved complete degradation contaminants within 15 min electrochemical activity remained after five cycles. Results demonstrate using functionalized FeCu improves efficiency offers an eco-friendly cost-effective alternative.
