Efficient removal of sodium pentachlorophenol with dioxygen activated by Fe@Fe2O3 and tetrapolyphosphate

摘要：

　　In this study,we demonstrate that sodium pentachlorophenol (NaPCP) could be efficiently degraded with dioxygen in air activated by Fe@Fe2O3 and tetrapolyphosphate (Air/Fe@Fe2O3/TPP).The process of dioxygen activation appeared to be a one-electron transfer route in this novel Air/Fe@Fe2O3/TPP system.Tetrapolyphosphate could increase the dissolved iron concentration,and then accelerate the conversion of for ·O2-to H2O2.Sodium pentachlorophenol was attacked by ·OH,resulting in the generation of tetrachloro-p-benzoquinone,tetrachloro-o-hydroquinone and tetrachloro-p-hydroquinone intermediates.These intermediates were further degraded into acids that eventually led to CO2 and H2O,companying with the release of chloride ion.
