Degradation of alizarin S in aqueous solutions was studied by use of ,60,Co γ-rays. Changes of absorption spectra, degree of decoloriation and total organic carbon (TOC) removal were investigated by changing the absorbed doses, primary concentration of alizarin S, the pH of the system, added amounts of H,2,O,2, and saturated with different gases in system, Results show that decoloriation and TOC removal efficiency is of 98 % and about 70 % respectively when the added concentration of H,2,O,2, was 4mmol/L and aqueous solution was saturated with air at 7.5kGy irradiation. The results suggested that the radiation technology might be a promising process for treatment of textile dye waste effluents.
