Abstract

<abstract abstract-type="main"> <title> <x xml:space="preserve">Abstract</x> </title> <p>Sulfate radical‐based advanced oxidation processes (SR‐AOPs) are attracting considerable attention due to the high oxidizing ability of sulfate radical to degrade organic pollutants in aqueous environments. In this study, the degradation of antibiotics amoxicillin using SR‐AOPs was investigated. This process is based on the generation of sulfate radicals through Co₃O₄‐mediated activation of peroxymonosulfate (PMS). Several parameters affecting antibiotics degradation such as Co₃O₄, PMS, pH, and temperature were investigated. The optimal conditions were found to be as follows: oxone concentration 0.01 mol·L ⁻¹, Co₃O₄ dosage 0.06 g, pH 6.0, reaction temperature 60°C, and reaction time 45 min. Under these optimum conditions, it was found that the chemical oxygen demand (COD) removal efficiency of 91.01% was achieved. The effect of ultrasound in the Co₃O₄/PMS system for amoxicillin degradation was also studied. © 2012 American Institute of Chemical Engineers Environ Prog, 32: 193‐197, 2013</p> </abstract>
