| Abstract: | The effect of absorbed dose on the decolouration of U(VI)-arsenazo-1 complex solutions has been investigated at pH 8.3. G-values were determined as a function of complex concentration as well as of OH, eaq– scavengers. Using competition kinetics, rate constants were determined and the degradation mechanism discussed. |
