Photocatalytic degradation and dechlorination mechanism of diclofenac using heterojunction Mn-doped tungsten trioxide (Mn-WO₃) nanoparticles under LED visible light from aqueous solutions.

ABSTRACT: The aim of this study was to investigate the photocatalytic mineralization and degradation of Diclofenac (DCF) using Mn-WO₃/LED in a photoreactor setup. The study analyzed the impact of operational variables, such as the initial concentration of DCF, pH level, reaction time, and catalyst dosage, on the degradation of DCF in the Mn-WO₃/LED process. The characteristics of Mn-WO₃ nanoparticles (NPs) were analyzed using a variety of techniques, including BET, TEM, XRD, TGA, FTIR, and FESEM. The results showed that the optimal conditions for achieving complete degradation of DCF were a pH of 7, a reaction time of 70 min, and a photocatalyst dosage of 2.2 g/L. To assess the toxicity of DCF and its degraded products, Daphnia Magna was used for toxicity analysis. I
