本文研究了在30％(V/V)TBP-煤油～HNO_3体系中亚硝酰钌在不同条件下的萃取行为。在~(106)Ru料液酸度与水酸度不同时,测定了放置时间和温度分配比的关系,并测得在0.5M硝酸附近的分配比呈极大值,但在~(106)Ru料液与水相的酸度相同时,分配比随水相硝酸浓度增加而缓慢增加。此外,增加有机相对铀的负荷度,将使分配比下降,而γ辐解产物中的MBP,DBP和羟肟酸对分配比的影响却不明显。
In this paper, the extraction behavior of ruthenium nitrosamides in 30% (V / V) TBP-kerosene ~ HNO 3 system under different conditions was studied. When the acidity of ~ (106) Ru solution was different from the acidity of water, the relationship between storage time and temperature distribution ratio was measured and the distribution ratio in the vicinity of 0.5M nitric acid was found to be very large. However, When the acidity of liquid and aqueous phase is the same, the distribution ratio increases slowly with the increase of nitric acid concentration in aqueous phase. In addition, increasing the loading of organic relative uranium will decrease the distribution ratio, while the effect of MBP, DBP and hydroxamic acid in the γ-radiolysis products on the distribution ratio is not obvious.
