Experimental Study of Degradation of Aniline in Water by Heterogeneous Catalytic Oxidation

Heterogeneous catalytic oxidation was used to treat aniline simulated wastewater.According to the ultraviolet adsorption curve and the change of CODCr before and after catalytic oxidation,decomposition mechanism of aniline by catalytic oxidation was discussed and analyzed.By investigating the effect of reaction time,dosage of oxidant,pH,initial wastewater concentrations on CODCr removal rate,the optimal processing condition was obtained.Over 97% CODCr removal rate of simulated wastewater was reached under the optimal processing condition.
