Formation and Control of Perchlorate during Electrocatalytic Oxidative Degradation of Ribavirin
摘要
Abstract
Ribavirin(RBV),a typical antiviral pharmaceutical,is frequently detected in aquatic environments,posting po-tential risks to human health and ecological safety.Electrocatalytic oxidation has been widely investigated for the treatment of pharmaceutical-containing wastewater,among various electrode materials,sub-stoichiometric titanium oxide(Ti4O7)anodes have attracted considerable attention due to their excellent characteristics.However,the formation patterns and control strate-gies of byproducts,such as chlorate(ClO3-)and perchlorate(ClO4-),during the electrochemical treatment of chloride-contain-ing wastewater by Ti4O7 still lack systematic investigation.This study compared the formation and control of perchlorate during the electrocatalytic oxidation of RBV using Ti4O7,BDD,PbO2,and RuO2/IrO2 anodes.The results show that the Ti4O7 anode ex-hibited the highest RBV removal efficiency in the chlorine-containing electrolyte,with a pseudo-first order reaction rate con-stant of 0.09 min-1 at a current of 300 mA.Moreover,the accumulation of ClO3-and ClO4-was significantly lower than that ob-served in the BDD system(0.000 46 vs.0.003 mol∙L-1 and 0 vs.67.1 μmol∙L-1 for ClO3-and ClO4-).By employing a carbon-polytetrafluoroethylene cathode for the in-situ electro-generation of hydrogen peroxide(H2O2),the oxidation chain leading to perchlorate formation was effectively interrupted,and neither ClO3-nor ClO4-was detected at a chloride concentration as high as 0.20 mol∙L-1.Liquid chromatography-mass spectrometry identified 13 degradation products,leading to the proposal of three primary pathways for the electrocatalytic degradation of RBV.ECOSAR prediction results indicate that the overall toxicity of the degradation products exhibited a decreasing trend throughout the reaction,and no highly toxic final products were generated.关键词
