| Summary: | ABSTRACT
The photocatalytic degradation has been considered to be an efficient process for degradation of organic
pollutants, which are present in the effluents released by industries. Thephotocatalytic bleaching was carried out on
rhodamin-B (cationic dye) in the presence of iron (III) complex, hydrogen peroxide and was observed
spectrophotometrically. The effect of various operating variables like pH, concentration of complex and dye, amount
of HzOzand light intensity etc. was also observed on the efficiency of the reaction. A tentative mechanism has also
been proposed for this photocatalytic degradation of rhodamin-B.
Keywords: Photocatalytic degradation, rhodamin-B, metal complexes, hydrogen peroxide.
