Abstract: Photochemical processes provide an attractive alternative to the conventional waste water treatment technologies. This paper summarizes studies on nitrobenzene photooxidation with a 125 W medium pressure UV lamp, using H2O2, as oxidant. The experiments are performed in an annular type photochemical, reactor or IL capacity. The rate and extent nitrobenzene destruction is assessed using various concentrations of H2O2. It is estimated that complete destruction of nitrobenzene can be achieved in 40 min at a H2O2 dose of 4.41× 10-5 mM/ L. Total Organic Carbon (TOC) and Total bound nitrogen (TNb) are also removed to an extent of 90 and 40% respectively after 1 h of UV exposure indicating photoperoxidation as a potential technique to decontaminate nitrobenzene in aqueous phase.
