The decolorization of reactive orange 16 dye (RO16) from aqueous solution by CuO/H(2)O(2) was investigated. The amount of dye removed was determined by measuring the concentration of the dye at its characteristic wavelengths by UV-Vis spectrophotometer. The effects of CuO dose, H(2)O(2) concentration and UV light on the decolorization of the dye were investigated. It was found that the removal rate increased with increasing mass of CuO and increasing concentration of H(2)O(2). The combination of CuO, H(2)O(2) and UV light was the best system with dye removal of 100% after 6 h. The removal efficiency observed was in the order: CuO/UV/H(2)O(2) > CuO/H(2)O(2) > CuO/UV = CuO > UV/H(2)O(2) > H(2)O(2) > UV.
