Abstract The reactions of ·OH and e-aq with AO7 in aqueous solutions were studied by nano-second pulse radiolysis techniques. The transient absorption spectra were attributed and the second order reaction rate constants were determined by following the buildup kinetics of the transient absorptions. In combination with the analysis of the UV-Vis absorption changes of AO7 after γ-radiolysis, the underlying reaction mechanisms were elucidated.
