摘要：

In this study the radiation-induced degradation of crystal violet ( CV) dye under various experimental conditions has been investigated. D-0.5, D-0.9 and D-0.99 values suggests that lower doses are required for 50%, 90% and 99% removal of CV dye when the sample solution contains excessive amount of 'OH radicals. The removal efficiency of CV dye in terms of G-values was also calculated under each reaction conditions. The results showed that 'OH radicals are playing effective role in the degradation of CV dye as compared to e(aq)(-) and 'H radicals. The gamma irradiation process effectively degraded CV dye at all pH values. The organic byproducts were examined and accordingly degradation pathway was proposed.
