Kinetic Investigation on the Photochemical Degradation of Brilliant Orange in the Presence of Hydrogen Peroxide

Abstract

The degradation of Brilliant Orange from aqueous solution was investigated by advanced oxidation process. Such oxidation process using
H2O2 in the presence of UV light is a feasible and efficient alternative for wastewater treatment from recalcitrant compounds such as
reactive dyes. H2O2 acts as an oxidant, produces .OH radical on irradiation by UV light. .OH radical oxidizes the dye. The disappearance of
Brilliant Orange was monitored on the basis of decolorization, determined by UV-absorption analysis. The extent of decolorization depends
on the relative ratio of initial concentrations of H2O2 to BO. The kinetic study of the degradation was investigated, by varying the initial
concentrations of BO and H2O2.
