Study on the Degradation of Nitrobenzene Utilizing Ultraviolet (UV) Radiation Process and the UV/ Hydrogen Peroxide Advanced Oxidation Process (AOP) |

The degradation of Nitrobenzene was investigated via ultraviolet (UV) radiation process and the UV/ hydrogen peroxide advanced oxidation process (AOP). Nitrobenzene (C6H5NO2) is hazardous both in acute and chronic exposure and has been found in leachate in landfills of the United States. Leachate is treated via conventional water treatment systems before entering the public drinking water supply. On the grounds that Nitrobenzene is only partially removed with conventional water treatment systems, there is a need to use alternative treatment processes. At this study, for Nitrobenzene tested, direct UV photolysis quantum yields were derived for use with monochromatic low pressure (LP) UV lamps and second-order hydrogen peroxide radical rate constant was developed. Utilizing these parameters, UV treatment of the Nitrobenzene in laboratory and natural waters were modeled. Nitrobenzene was more effectively degraded utilizing UV/H2O2 advanced oxidation as compared to direct UV photolysis treatment using LP lamps which omit UV 254 nm radiation. |
