چکیده

Study on the photocatalytic decolorization of aqueous solution of Direct Red 23, a commercial azo-reactive textile dye, in the presence of UV light radiation. The effect of different reaction parameters on the photo catalyst of DR 23 was assessed best operational parameters were observed as photons: catalyst loading 1gm-3.0gm/50ml, pH 3.5-11.5, temperature 303k,dye concentration10mg/50ml-70mg/50ml and 2.30hrs light irradiation on photo decolorization. FTIR is employed successfully to study the behavior of dowex-11 Resin and after the immobilized by Methylene blue dye. FTIR spectrum is recorded in the range 400-4000cm-1.Activity of photo catalyst MBIR-11 remains impervious on continuous use.
