Abstract
H2O2/UV and O3/UV oxidized nitrobenzene in water with an initial nitrobenzene concentration of 0.15 mM, inorganic carbon concentration of 0.8 mM and pH 7 at a rate of 1.13 • 10-8 and 2.68 • 10 -8 M/sec, respectively. Oxidation by ozonation offered a comparable rate of 2.02 • 10-8 M/sec with O3/UV under similar operating conditions. At higher ozone dosages, ozonation also resulted in appreciable nitrobenzene removal rates. Nitrobenzene promoted radical reactions in the ozonation process. On the other hand, these radical-promoting reactions were strongly inhibited at an inorganic carbon concentration of 4 mM. For O3/UV treatment, the nitrobenzene removal rate decreased when the inorganic carbon concentration was increased from 0.8 to 4 mM. This decrease, however, was not as great in O3/UV as in ozonation, since the nitrobenzene-promoted radical reactions are less important in O3/UV. An increase in pH in the range of 5 to 10 adversely affected the nitrobenzene removal for the same process.
