Decolorization of Textile Wastewater by Solar Light and Ultraviolet Radiation
In this study solar light and UV radiation were used to decolourize textile wastewater samples that were green, purple and orange. The effect of them has also been investigated in presence of H2O2. The percentage of colour removal in maximum wavelength of each mixed dyes, that were made by using blue, red and yellow dyes, have been measured. The results have shown that purple and green dyes have maximum and minimum of decolorization percentage of 99.0 and 96.0 respectively with UV light at 90 minuets in presence of 0.5 M H2O2. By using solar radiation for these samples it can be seen that the maximum percentage of decolorization was 99.5 in presence of 0.5 M H2O2 which also happened for green dye after 4 hours. The colour removal of orange dye was the minimum under the above conditions.
