Problem statement: In present study, we selected a model dyes Ponceau S and Sudan IV, totest a recently developed photo catalyst methylene blue immobilized resin dowex-11.
Approach: This isa light-activated process that has been successfully applied to remove organic and inorganic dyes oftextile industries.
Results: The reactor, made of glass slides (tubes) coated with a thin-film ofmethylene 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 variousconditions (with/without catalyst, with/without light radiation, variation in catalyst amount, dyesconcentration, light intensities and pH).
Conclusion: The ponceau S and sudan-IV, removalefficiency was evaluated using UV/Visible spectrophotometer at &lambda max = 514±2 nm Ponceau S and &lambda max = 520 nm respectively removal efficiency results (99%) after 3 h at pH 9) showed that new photocatalyst, methylene blue immobilized resin dowex-11 provided a promising technology to improve thequality of effluent from textile wastewater treatment plants.
