Research output: Contribution to journalReview article

119 Citations (Scopus)


The radiation-induced decolouration and degradation of aqueous solutions of azo dyes and their model compounds (anilines, phenols, triazines) are reviewed together with practical applications and the experimental methods (pulse radiolysis, steady-state gamma radiolysis, as well as end-product analysis) used for studying the reactions. The proposed mechanisms and the rate coefficients for the reactions of {radical dot}OH, eaq- and {radical dot}H water radiolysis intermediates with the dye molecules and with model compounds are summarized.
