摘要：

The effect of high-energy radiation on Acid Red I (ARI) azo-dye solution was investigated by UV-Vis spectroscopy and chemical oxygen demand (COD) measurements. Doses in the order of 10 kGy cause complete decolouration of the 10(-3)-10(-4) mol dm(-3) solutions; however, for complete mineralization doses higher by 1-2 order of magnitude are needed. Hydrated electrons and H-circle atom are more effective in fading reaction, while the (OH)-O-circle radicals have higher efficiency in mineralization. The HO2 circle/O-2(circle-) radical-radical anion pair is rather inefficient in fading reaction. (C) 2007 Elsevier Ltd. All rights reserved.
