Heterogeneous photocatalysis is emerging as a sustainable technology for solving environmental problems that overcomes many of the drawbacks of the traditional water treatment methods. Transformation of Azo dyes is challenging for researchers and environmentalists. Transformation of these azo dyes by recently developed photo catalyst Methylene Blue immobilized Resin Dowex-11 is better alternate to replace costly traditional treatment technologies for industrial application. A result of experiment is exiting and we recover 100% transparent water from dye polluted wastewater. We use Acid red-8 as model azo dye for experimental purpose. The rate of transformation is determined spectrophotometrically by varying pH, light intensity, dye concentration and amount of catalyst.
