Wet process of 2,4,6-trinitrophenol by Fenton and photo-Fenton processes(DEPARTMENT OF APPLIED CHEMISTRY AND BIOCHENISTRY)

Wet oxidation treatment of 2,4,6-trinitrophenol of the aromatic nitro compound was studied by the Fenton and photo-Fenton methods. As Fenton reagents, the mixture of hydrogen peroxide and Ferrous or Ferric ion was used. Though Fenton method could decompose 2,4,6-trinitrophenol, TOC was not decreased. Photo-Fenton method could decompose 2,4,6-trinitrophenol and remove TOC efficiently. It was confirmed that nitro group in 2,4,6-trinitrophenol was converted to nitrate or nitrite ion for both methods. Under irradiation(photo-Fenton method), Fenton reagent of the mixture of hydrogen peroxide and ferric ion can treat 2,4,6-trinitrophenol more effectively than that of the mixture of hydrogen peroxide and ferrous io
