Tungsten Trioxide (WO₃)-assisted Photocatalytic Degradation of Amoxicillin by Simulated Solar Irradiation.

ABSTRACT: This study investigates the photocatalytic degradation of amoxicillin (AMO) by simulated solar irradiation using WO₃ as a catalyst. A three-factor-three-level Box-Behnken design (BBD) consisting of 30 experimental runs is employed with three independent variables: initial AMO concentration, catalyst dosage, and pH. The experimental results are analyzed in terms of AMO degradation and mineralization, the latter of which is measured using dissolved organic carbon (DOC). The results show that the photocatalytic degradation of AMO follows pseudo-first-order kinetics. AMO degradation efficiency and the pseudo-first-order rate constants decrease with increasing initial AMO concentration and pH and increase with increasing catalyst dosage. Though AMO degradation is almost fully complet
