| 摘 要： | 以H2O2为催化剂,考察了无机盐的加入对H2O2催化脱色甲基橙溶液的影响。结果表明:KBr对脱色反应有促进作用,而且KBr的加入量存在最佳值;Na2CO3的加入在实验范围内对脱色反应有一定抑制作用,随着加入量的增加抑制作用逐渐减弱;Na2SO4的存在对甲基橙的脱色反应没有影响。K2S2O8和H2O2之间存在加和作用。KBrO3和KIO3的存在对反应有抑制作用。KIO4与H2O2共存在暗态对甲基橙就有很好的脱色效果,而且H2O2的量有最佳值。

| Abstract: | H2O2 was used to decolorize of methyl orange(MO) solution with ultraviolet radiation or not.Influence of inorganic salts on photocatalytic decolorization of methyl orange with H2O2 was investigated in details.The results indicated that KBr could promote the decolorization reaction,there was an optimal amount of KBr in this case.Na2CO3 could inhibite the decolorization reaction,the degree of effect became weaker with the increasing of amount.While Na2SO4 had no obvious influence on the decolorization reactio... |
