Abstract
The degradation of nitrobenzene, a recalcitrant compound, using the combination of ozone with UV radiation and UV+Fe(III) has been carried out in a 21 L reactor and compared with results obtained from single ozonation. Whereas TOC elimination was not improved by using UV radiation, the addition of Fe(III) (O 3/UV/Fe(III)) enhanced the mineralization rate. The principal effect of Fe(III) on the photolytic ozonation is attributed to the photodecarboxilation of ferric ion complexes.
