Reater the percentage of U(VI) and Th(IV) inside the HOP. An exception is the fact that for 1.2 M TBP and six of U(VI)3, the Th(IV) in the HOP. An exception isthe lowest ofM TBP conditionsHNO3 , M HNO and percentages of actinides in DOP are that for 1.2 each of the and 6 M tested. the percentages of actinides in DOP are of actinides of each of the circumstances tested. For this For this sample, the total concentration the lowest in the organic phase just before splitting sample, the total concentration of actinides within the organicthe supersaturation ofwas slightly was slightly lower than inside the other cases. Because of this, phase ahead of splitting the organic reduce than in splitting is decrease than in other cases. The U/Th of the organic phase prior to phase prior to the other circumstances. As a result, the supersaturation ratios within the HOP obtained splitting is reduce than in other instances. The U/Th ratios within the HOP obtained have been in between had been among two.9 and 5.five; the lowest values had been obtained for the lowest TBP concentra2.9 and five.5; the lowest values had been obtained for the lowest TBP concentration of 0.eight M. The tion of 0.eight M. The highest values had been observed for 1 M and 1.2 M TBP for 5 M HNO3. For highest values had been observed for 1 M and 1.2 M TBP for 5 M HNO3 . For the other HNO3 the other HNO3 concentrations, the U/Th ratios obtained for 1 M and 1.two M TBP are close, concentrations, the U/Th ratios obtained for 1 M and 1.2 M TBP are close, with an average with an typical value of 4.4. value of 4.4. These experiments show that for experimental situations varying around 1 M TBP These experiments show that for experimental situations varying about 1 M TBP and and 6 M aqueous HNO3, fascinating separations is often obtained as long as the supersat6 M aqueous HNO3 , fascinating separations might be obtained so long as the supersaturation uration from the organic phase obtained at 70 is adequate. Having said that, a compromise will have to in the organic phase obtained at 70 C is adequate. Having said that, a compromise should be created be produced involving the amount of Th(IV) segregated inside the HOP and U/Th ratio in the HOP: among the quantity of Th(IV) segregated inside the HOP and U/Th ratio within the HOP: when when the quantity of Th(IV) segregated in HOP is maximized, this results in a greater U/Th the quantity of Th(IV) segregated in HOP is maximized, this results in a larger U/Th ratio. ratio. case of nuclear fuel recycling, it can be preferable to target target yield of Pu(IV) inside the In the Within the case of nuclear fuel recycling, it can be preferable to a higher a higher yield of Pu(IV) within the HOP, simply because the needs lie with regards to plutonium recovery efficiency. In all HOP, since the specifications lie with regards to plutonium recovery efficiency. In all cases, situations, the two Aztreonam manufacturer phases had been very easily separated, without having any peculiar difficulty in the course of phase the two organicorganic phases had been effortlessly separated, without having any peculiar difficulty in the course of phase disengagement. The final viscosities of HOP to lie involving 4 and 16.5 mPa , disengagement. The final viscosities of HOP had been foundwere discovered to lie among 4 and 16.five mPa.s, around 0.eight mPa , in comparison comparison for an initial for TBP organic and of DOP and of DOP about 0.eight mPa.s, in with 0.9 mPawith 0.9 mPa.s 1 Man initial 1 M TBP organic phase in phase in n-dodecane. n-dodecane. 2.three.
