Photochemical degradation contributes
to the environmental fate of many pesticides, chemicals, and industrial waste in
surface waters. Photochemical degradation (PCD) of Nitrobenzene (NB) has
been studied using a UV light source and Fenton reagent under different
experimental conditions. The effect of concentration on PCD of NB was monitored
and recorded in the range 0.5 x10-4M to 3.0x10-4M. The
concentration of H2O2 was performed from 5.0 x10-4M
to 2.5 x10-4M and Fe(II) from
1.0 x10-4M to 5.0 x10-4M respectively.In terms of concentration, the
absorbance increases with increasing the concentration of the solution of NB, H2O2
and Fe(II). The initial rate of PCD was
recorded at fixed pH 2.42 of solution. Two optimums for pH were found for PCD
of Nitrobenzene ranging from pH 2.42 to 4.20. The intermediates formed during
PCD of NB were identified, by which a mechanism was then suggested that PCD is
actually found to follow pseudo first order kinetics.
