Abstract
from aqueous medium using the Photo- Fenton process. The Fenton reagent that consists of a mixture of hydrogen peroxide (H2O2) and Ferrous ions (Fe+2) was used to generate the hydroxyl radicals ( . OH) that attacks the target contaminant and degrade it. The influence of the main parameters (concentration of Dye (RR198), concentration of photocatalyst (Fenton reagent, H2O2 and pH) that govern the degradation kinetics was evaluated. The optimum conditions for the photobleaching of dye had been established. The kinetics of degradation of the dye in the dilute aqueous solutions follows first order kinetics. Complete mineralization of dye RR198 is achieved by Photo- Fenton reagent. The photobleaching process follows first order kinetics in respect to Langmuir-Hinshelwood model
