Answer: 3PuO2 + *HNO3 3PuO2(NO3)2 + 4H2O + 2NO
The principle of solvent extraction is a distribution of species between two immiscible liquid phases. To reach the partition equilibrium between contacted phases faster, this two-phase mixture is vigorously agitated for required time. In PUREX, aqueous phase is the nitric acid solution of the spent fuel, organic phase is the 30 vol.% TBP (tributyl phosphate) in alkane (kerosene) diluent. Finish the equations for their extraction equilibria with TBP and identify (bold font) the extracted compound they form with TBP on the interface, which is then transferred into bulk organic phase:
Pu4+ + TBP + ? -> b) UO22+ + TBP + ? ->
