The Catalytic Degradation of the Inflammatory Drug Diclofenac Sodium in Water by Fe2+/Persulfate, Fe2+/Peroxymonosulfate and Fe2+/H2O2 Processes: A Comparative Analysis

Diclofenac sodium was extensively used for treating arthritis, osteoarthritis and skeletal muscular injuries, which ultimately caused troubles aquatic organisms as well human beings. In this study, homogeneous catalytic advanced oxidation processes, including Fe2+/persulfate, Fe2+/peroxymonosulfate Fe2+/H2O2, were the degradation of diclofenac in water, without using UV-C light. About 89, 82 54% DCF decomposed by respectively, 60 min. The followed pseudo first-order kinetics, all cases. efficiency significantly affected presence various anions, such NO3−, HCO3− SO42−. mineralization studies revealed 62, 45 32% total carbon removal addition, byproducts determined FTIR analysis. results that Fe2+/oxidant system, particularly a promising technology elimination toxic pharmaceuticals, sodium, from water environment.
