Wan Musa, Wan Abdul Rahim (2017) Comparative study of photodegration of orange by solar and fenton process / Wan Abdul Rahim Wan Musa. [Student Project] (Unpublished)


Wastewater is exhausted in large volume every year due to the processes of textile industries
such as dyeing am finishing processes. Nowadays, more than 50% of dyes used in textile
industry are Azo-based dyes. Inorganic salts improve the coloration of the dye, which
enhances the pollution load of wastewater from textile industries. Degradation of the reactive
textile dye Orange Gelb (OG) was studied using Fenton's Reagent of Advanced Oxidation
Processes (AOPs) and solar photo catalytic by TiO2. A laboratory set-up was designed to
evaluate the effectiveness for both treatment. The initial concentration of OG in the reaction
was 5 ppm. The effects of irradiation time and the condition of pH dye and concentrations of
catalyst (TiO2, H2O2 and FeSO4) on the degree of degradation efficiency were studied. The
results indicated that photo-Fenton's process is more effective than solar photo degradation
by TiO2. The degradation effectiveness of Fenton's procedure was up to 79.22% in 2 hour
rate at pH 3 and in 3.1 X 10-2 M, while the degradation efficiency of TiO2 was just up 19.75%
at pH6 am in 5 ppm The degradation effectiveness of Fenton process increased as the
concentration of OG dye decreased, the concentration of H202 increased, concentration of
FeSO4 increased and pH value get decreased which is in more acidic. While for photo
degradation for TiO2, the best degradation happened when TiO2 concentration increased,
concentration of OG dye decreased, and ph value increased.
