Removal of crystal violet dye from aqueous solution by gamma irradiation

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_0.99values 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
