The irradiation-induced degradation of an azo dye, Alizarin Yellow GG (AY-GG), was investigated in aqueous solution under gamma irradiation using a 60 Cobalt source at a dose rate of 113Gy/min. The decolorization percentage of AY-GG reached 65% when its initial concentration was 100mg/l and the absorbed dose was 9kGy. The decolorization process could be described by first-order kinetic equation...
