The Investigation of Methyl Orange Dye Degradation With the Help of Photochemical of Fe (III)

Photo catalytic studies have recently received a great deal of attention from different fields of study. Semi conductive heterogeneous photo catalyses and homogeneous photo catalyses such as Fe (III) salts can perform Redox reactions in the presence of different substrates by absorbing light in ultraviolet or visible area. This photo catalytic characteristic can be used to remove pollutants. With regard to the advantages of Fe (III) over heterogeneous catalysts, its photo catalytic activity was studied in the presence of potassium proxy di sulfate and the use of visible light as the light source. Experiments are carried out to examine the degradation of Methyl Orange dye as an azoic dye which has a wide application in textile industry. The degradation of the above mentioned dye occurred in different conditions and it was realized that light and Fe (III) are necessary for its degradation. Degradation reactions occurred in darkness too. The presence of -2 propanol as radical receptor didn’t have deterrent effect in these reactions. Studies show that Fe (III) and potassium proxy di sulfate solution has the degradation capacity for the above dye in the presence of light and this activity is, in some cases, due to hydroxide radical production.
