| Abstract: | kinds of dye solution, including 6 species of cationic, direct, reactive, acidic, reductive and disperse dye were reacted with Fentons reagent. The four formers were decolorized and the concentrations of TOC of them were decreased during 180 min.On the contrary the colority and the TOC of the two latters were reduced lightly. The catalytic function of different metal ions and UV light on the decomposite of Rodamine B was in the sequence of Fe2+/UV>Cu2+/UV>Fe2+>Cu2+>Mn2+/UV>Ag+/UV>Mn2+>Ag+.Vat Blue RSN dye solution was degradated by Fentons reagent, Fenton/UV and H2O2/UV. The oxidation by Fenton/UV was the strongest and even stronger than the arithmetic sum of the other two, which means the synergistic effect of UV and Fe2+ on the function of H2O2. |
