Autor: R, Musat, J L, Marignier, C, Le Naour, S, Denisov, L, Venault, Ph, Moisy, M, Mostafavi

Publikováno v: Physical chemistry chemical physics : PCCP. 22(9)

Concentrated nitric acid solutions subjected to radiation produce radicals of extreme importance in the reprocessing of spent nuclear fuel. Knowledge of the different rate constants of the reactions involved in this chemistry is needed to improve the

Degradation of Erioglaucine Dye Under γ-irradiation

Autor: H.-B. Yang, L. Venault, F. Azar, S. Faure

Publikováno v: Procedia Chemistry. 7:647-653

The kinetics and the mechanism degradation of erioglaucine dye in aqueous solution irradiated under γ-rays from 60Co are investigated. From the results of the absorption UV-Vis spectra of 0.7 mM erioglaucine solution as function of dose, the concent
