Photo Degradation of Industrial Dye Using ZnO as Photo Catalyst (original) (raw)

In this study, the potential of a common semiconductor, ZnO, has been explored as an effective photocatalyst for the photodegradation of model dye: Methylene Blue, a commonly used textile dye. Using advanced oxidation processes (AOPs), ZnO appears to be a suitable alternative to TiO2 for water treatment. The experiments were carried out by irradiating the aqueous solution of dye containing photocatalysts with UV light. Here, a detailed investigation of the effects of process parameters like catalyst loading, initial dye concentration, presence of hydrogen peroxide and pH on the extent of photodegradation have been presented. Hence, it may be a viable technique for the safe disposal of textile wastewater into the water streams.
