摘要
Abstract
To explore the properties and mechanism of electrogenic hydrogen peroxide(H2O2)on different electrode materials,graphite,titanium,stainless steel,and iridium tantalum were selected as cathode materials,and levofloxacin(LVF)degradation experiments were carried out in combination with zero-valent iron(nZVI).The properties of electrogenic hydrogen peroxide at different pH on different cathode materials were investigated,and graphite was used as the cathode material to study ions effects on electrogenic H2O2 and the degradation mechanism of LVF.The results show that electrogenic H2O2 has the best performance when graphite is used as the cathode material,and H2O2 is generated by single-electron and two-electron pathways.At pH=3,graphite can effectively degrade LVF by forming·OH and electron direct transfer(DET).The experimental results show that graphite as a cathode can effectively degrade LVF and efficiently produce H2O2,which provides data for the Fenton-like technology of electrogenic hydrogen peroxide.关键词
