| 摘 要： | Nine kinds of reactive dye solutions: Reactive K-2RL, H-E2R, X-6B1Y, HE-4G, X-3B, K-2R,H-E7B, X-4RN and S-F3B were treated by usingFenton reagent. While the concentration of dye is 400mg/L, the FeSO_4 dosage 100-180 mg/L, H_2O_2 240～540 mg/L, that is the stoichiometric numbers of Fe~(2+)and H_2O_2. are between 1: 9～1: 12, pH=3, reaction

| Abstract: | Nine kinds of reactive dye solutions: Reactive K-2RL, H-E2R, X-6B1Y, HE-4G, X-3B, K-2R,H-E7B, X-4RN and S-F3B were treated by using Fenton reagent. While the concentration of dye is 400mg/L, the FeSO4 dosage 100～180 mg/L, H2O2240～S40 mg/L, that is the stoichiometric numbers of Fe2+and H2O2 are between 1:9～1:12, pH=3, reaction time l h, temperature 25℃, the colority removal efficiency reach more than 95%, the COD removal efficiency 65%～8S%, and the TOC removal efficiency 70.2%. By comparing UV-VIS absorption spectrum before and after treatment, it further shows that decomposition effect of Fenton reagent on these nine kinds of reactive dyes is satisfactory. |
