摘要:

The effect of absorbed dose on the absorption spectra of arsenazo-1 solutions at different concentrations and different pH,s was investigated. Increase of absorbed dose was found to decrease absorption at characteristic peaks. Decolouration yields (G-values) were calculated for the different solutions. The radiolysis of arsenazo-1 solution was also investigated in presence of varying concentrations of methyl alcohol. Using competition kinetics, degradation mechanism was discussed.
