| Popis: | The radiolysis of binary mixtures containing tributyl phosphate (TBP) and ali-phatic or aromatic hydrocarbons is discussed. The radiation-chemical stability of the irradiated systems was measured according to the yields of the acid esters (di- and monobutyl phosphate) and gaseous products, as welI as according to the change in the distribution coef ficients of plutonium and zirconium between the irradiated organic phase and an aqueous solution containing 2M nitric acid and the nitrates of these metals. The concentration dependence of the radiation chemical yields of gaseous and acid radiolysis products gives evidence of a deviation from the additivity rule and of a transfer of energy from the aliphatic hydrocarbon to TBP. As a result of replacement of the aliphatic hydrocarbon by an aromatic hydrocarbon, the yields of the radiolysis products are sharply reduced. The influence of aromatic hydrocarbons upon the radiation-chemical stability of TBP is confirmed by data on the distribution coefficients of plutonium and zirconium, the values of which are determined to a considerable degree by the content of dibutyl phosphate-the basic product of the radiolysis of TBP. |
