不同pH条件下Fe^(2+)/Fe^(3+)/Ni^(2+)/O_3体系对活性艳蓝X-BR的催化氧化

Catalytic Ozonation of Reactive Blue X-BR by Fe^(2+)/Fe^(3+)/Ni^(2+)/O_3 Under Different pH Conditions

臭氧和催化臭氧氧化法是对印染废水有效的处理手段之一。选取用途较广的活性艳蓝X-BR为研究对象,探讨了氧化过程中染料的降解和结构变化情况。并选取了Fe2+、Fe3+和Ni2+为均相催化剂,讨论了pH对催化效果的影响。实验表明,均相催化体系中,酸性条件下更有利。

With the presence of some transition metal ions Such as Fe2+,Fe3+ and Ni2+ forming a homogeneous catalyst,ozonation of reactive blue dye becomes more effective in utilizing O3.Condition of pH,under which the ozonation takes place,is investigated.
