摘要：
Both citrate and hypophosphite in aqueous solution were degraded by advanced oxidation processes(Fe2+/H2O2,UV/Fe2+/H2O2,and electrolysis/Fe2+/H2O2) in this study. Comparison of these techniques in oxidation efficiency was undertaken. It was found that Fenton process could not completely degrade citrate in the presence of hypophosphite since it caused a series inhibition. Therefore,UV light(photo-Fenton) or electron current(electro-Fenton) was applied to improve the degradation efficiency of the Fenton process. Results showed that both photo-Fenton and electro-Fenton processes could overcome the inhibition of hypophosphite,especially the electro-Fenton.
