Problem statement: In present study, we selected a model dyes Ponceau S and Sudan IV, to test a recently developed photo catalyst methylene blue immobilized resin dowex-11. Approach: This is a light-activated process that has been successfully applied to remove organic and inorganic dyes of textile industries. Results: The reactor, made of glass slides (tubes) coated with a thin-film of methylene blue immobilized resin dowex-11 with the help of a suitable and non-reactive adhesive. Dye solution was continues recycles from reactor for 3 h in a recirculation mode under various conditions (with/without catalyst, with/without light radiation, variation in catalyst amount, dyes concentration, light intensities and pH). Conclusion: The ponceau S and sudan-IV, removal efficiency was evaluated using UV/Visible spectrophotometer at λmax = 514±2 nm Ponceau S and λMax = 520 nm respectively removal efficiency results (99%) after 3 h at pH 9) showed that new photo catalyst, methylene blue immobilized resin dowex-11 provided a promising technology to improve the quality of effluent from textile wastewater treatment plants.
