| 摘 要： | 采用UV/Fenton法降解甲基绿溶液,探讨了H2O2浓度、Fe2 浓度以及pH值对甲基绿脱色率与去除率的影响.UV对甲基绿光降解反应的速率起促进作用,H2O2浓度决定甲基绿的去除率,Fe2 浓度是影响降解速率的主导因素,而随pH值降低甲基绿反应速率明显增大.比较了甲基绿在光降解过程中的色度去除率和总有机碳(TOC)去除率之间的关系,表明总有机碳去除率滞后于色度去除率.

| Abstract: | The methyl green solution was treated by the UV/Fenton reagent under operational conditions(e.g.) initial concentration of H_2O_2.Fe~(2+)and pH value.It can be conclude that UV had a positive effect on the degradation,the removal of methyl green was determined by the H_2O_2 concentration,while Fe~(2+) concentration was the key factor affecting the degradation rate and the degradation ratio was increasing with decreasing pH value.Meanwhile the change of TOC of the methyl orange solution with the reaction time was discussed and the rate of degradation was faster than that of TOC removal rate. |
