摘要：
The radiation-chemical discoloration of evacuated alcoholic solutions of the azo dye 1-(2-pyridyl-azo)-2-naphthol was studied using a pulse radiolysis technique. The spectral characteristics of radicals were determined, and the radiation-chemical yields of their formation and dye decomposition were measured. The degradation of the azo dye Acid Yellow 99 under irradiation with gamma-quanta and vacuum UV radiation was compared. The radical mechanism of azo dye degradation in aqueous and alcoholic solutions under exposure to high-energy particles was confirmed.
