Treatment of Aniline-contaminated Wastewater using Oxidation Reagent

산화제를 이용한 아닐린 폐수처리

This work carried out the removal of aniline by wet oxidation in aqueous solutions like a industrial wastewater using Ozone, UV, and Ozone-UV . The main features of this experiment are as follows: the aniline was decomposed by OH and HO$_{2}$ radicals which produced from the reaction of water with UV and Ozone, when the Ozorie and Ozone-UV used the aniline was decomposed completely. The decomposition of aniline was very fast reaction and the reaction times were within 10min. and 20min. in case of for Ozone Ozone-UV respectively. Assumed simplified reaction mechanism from the aniline oxidation model, and the we are calculated the theoretical reaction rate constants by computer simulation, and then compared with experimental data. We suggest that this simulation program is applicable to estimate of the aniline decaying concentration and removal efficiency of aniline - contaminated wastewater.
