The Experiment Study of Nitrobenzene Polluted Groundwater by Catalytic Oxidation

Abstract:

Article Preview

The catalytic ozonation which treated nitrobenzene in extracted groundwater with high concentration was studied.The experiment showed that the optimization of catalysts was that the manganese nitrate and iron nitrate were dissolved to dip the activated alumina in 10 percent of mass concentration, the ratio of manganese to iron was 2:1, the calcination temperature was 450°C with six hours. The catalyst was characterized by SEM-EDS too; Adsorption of catalyst, air stripping, increasing concentration, temperature and pH all had effect on this reaction system. When pH was 9,temperature was 25 °C and catalyst dosage was 30g/L, the removal rate of nitrobenzene could reach 68.8%.
