摘要
文中将过氧化氢和蜂窝陶瓷作为联合催化剂,用于催化臭氧化去除水中微量硝基苯,研究了过氧化氢和蜂窝陶瓷联用对臭氧化反应的催化效能,考察了催化剂用量、溶液pH值、碱度对硝基苯氧化效率的影响规律,发现蜂窝陶瓷使用30次后的催化活性没有明显变化。
Hydrogen peroxide and ceramic honeycomb are combined to catalyze ozonation for the removal of trace nitrobenzene in aqueous solution. The activity of combined catalysts toward ozonation is studied. The effects of various factors on the catalytic oxidation are investigated, such as the amount of catalysts, the pH value and alkalinity. It is also found that there is no change of activity in catalytic ozonation after ceramic honeycombs being continuously used about 30 times.
