Abstract
In this work we performed a comparative study regarding the performance characteristics of three photochemical treatments for Brilliant Blue degradation: photolysis (only UV radiation), irradiation in the presence of H2O2 (H2O2 /UV), photo-Fenton reaction (Fe2+/H2O2 /UV). The kinetic analysis revealed that BB degradation follows an apparent first order kinetics. The examination of the estimated rate constants and the degradation efficiencies revealed the superior performance of the photo-Fenton oxidation, which may be due an increased gain of reactive oxygen species species comparative to the UV or UV/H2O2 treatment.
