Abstract: The photodegradation of Rhodamine B and Congo red dye solutions were studied in presence of yttrium oxide. The rate constant of the photodegradation process was calculated. The effects of pH values, sun light, UV lamps, the dye concentration, and the dose of Y2O3 on the rate of photodegradation were studied. Also the kinetic parameters by using Longmireequation were calculated. The carbon oxygen demand (COD) and the total organic carbon (TOC) were determined. The analysis of the obtained results indicate that photodegradation of the both dyes depend on the structure of the dyes, the function groups of the dyes, the pH value of the media, the dose of the catalyst and the concentration of the dyes.
Keywords: Photodegradtion, Dyes mineralization, Rhodamine B, Congo red and yttrium oxide.
