Synergetic Photocatalytic Peroxymonosulfate Oxidation of Benzotriazole by Copper Ferrite Spinel: Factors and Mechanism Analysis

Toxics, Journal Year: 2023, Volume and Issue: 11(5), P. 429 - 429

Published: May 4, 2023

The development of oxidation processes with the efficient generation powerful radicals is most interesting and thought-provoking dimension peroxymonosulfate (PMS) activation. This study reports successful preparation a magnetic spinel CuFe2O4 using facile, non-toxic, cost-efficient co-precipitation method. prepared material exhibited synergetic effect photocatalytic PMS oxidation, which was effective in degrading recalcitrant benzotriazole (BTA). Moreover, central composite design (CCD) analysis confirmed that highest BTA degradation rate reached 81.4% after 70 min irradiation time under optimum operating conditions = 0.4 g L-1, 2 mM, 20 mg L-1. Furthermore, active species capture experiments conducted this revealed influence various species, including •OH, SO4•-, O2•-, h+ CuFe2O4/UV/PMS system. results showed SO4•- played predominant role photodegradation. combination photocatalysis activation enhanced consumption metal ions redox cycle reactions, thus minimizing ion leaching. Additionally, maintained reusability catalyst reasonable mineralization efficiency, more than 40% total organic carbon removal four batch experiments. presence common inorganic anions found to have retardant on order retardation following: HCO3- > Cl- NO3- SO42-. Overall, work demonstrated simple environmentally benign strategy exploit synergy between activity for treatment wastewater contaminated widely used industrial chemicals such as BTA.
