摘要 在实验条件下 ,金属离子对甲基橙光化学降解的影响较小 ,其顺序为 Fe2 + >Y3 + =La3 + >Mn2 + =Zn2 + .氧化剂对甲基橙光化学降解有较强的影响 ,其顺序为 KIO4 >K2 S2 O8>KBr O3 ≈H2 O2 .Mn2 + +KIO4 ,H2 O2 +Fe2 +对甲基橙光化学降解的影响非常显著 . Under experimental conditions, metal ions have few effects on the photochemical degradation of methyl orange, the sequence is Fe 2+ >Y 3+ =La 3+ >Mn 2+ =Zn 2+ . Oxidants have stronger effects on the photochemical degradation of methyl orange, the sequence is KIO 4>K 2S 2O 8> KBrO 3≈H 2O 2. The effects of Mn 2+ +KIO 4 and H 2O 2+Fe 2+ are very striking.
