| 中文摘要 |
| 以吐氏酸的臭氧氧化为例,研究了过渡金属镍、铁、铜单组分和不同配比双组分氧化物的催化作用。附着沉淀法制备的Ni-Fe(1:4)和Ni-Cu(4:1)催化剂的臭氧利用率分别比γ-Al2O3载体提高了28.9%和24.3%.金属氧化物催化臭氧化能显着改善吐氏酸溶液的可生化性,当臭氧消耗量为0.25-0.35g/L时,BOD5/COD达到最大值0.28. |
| 英文摘要 |
| This paper studied the property of oxides of nickel,ferrite and copper or their two components mixture that catalyzed ozonation of tobias acid solution,one of important dye intermediates.Ni Fe(1:4) and Ni Cu(4:1) catalysts which were prepared by the adsorption precipitation method performed the highest activity,their ozone utilization efficiency is 28.9% and 24.3% higher than the γ-Al2O3 carrier respectively.In the process of catalyzed ozonation,biodegradability of solution was greatly improved,and BOD5/COD rose to the maximum value of 0.28 as the ozone dosage was 0.25-0.35g/L. |
