| 摘 要： | 以NO-3为光催化剂，在紫外灯照射下，对甲基橙溶液进行光催化脱色。结果表明，叔丁醇、甲醇和乙醇对催化脱色反应有抑制作用; KBr和Na2SO4对脱色反应均有促进作用;而且KBr的加入量存在最佳值; Na2SO4的促进作用随Na2SO4的量的增加逐渐增强。Na2CO3的存在对甲基橙的脱色反应没有影响。K2S3O8和NO-3之间存在较强的协同作用；KIO3和NO-3之间存在相加作用；KBrO3和NO-3之间存在拮抗作用。

| Abstract: | The NO-3 was used to decolorize the methyl orange (MO) solution with ultraviolet radiation. Influence of several reagents on photocatalytic decolorization of methyl orange with NO-3 was investigated. The results indicate that t-BuOH, ethanol and methanol can press the decolorization reaction, KBr and Na2SO4 can promote the decolorization reaction, there is an optimal amount of KBr in this case and the effects of Na2SO4 increase with the concentrations, while Na2CO3 has no obvious influence on the decolorization reaction. The synergy between K2S2O8 and NO-3 is very strong.There is no synergy between KIO3 and NO-3, while there is inhibitation between KBrO3 and NO-3. |
