Abstract

The photocatalytic degradation of azo dye which is generally used in textile industry, acid red 73 in presence of methylene blue immobilized resin (MBIR) Dowex 11 with solar light in aqueous solution has been studied. The operational parameters such as dye concentration, catalyst loading, pH and light intensity were investigated during the process. The experiment was carried out by irradiation the aqueous solution of dyes containing photocatalyst with solar light and UV. The results showed that the optimum degradation larger than 92% of acid red 73 was observed in around 160 min. at room temperature at 7.5 pH and catalyst loading in around 2.0 gm.
