Solvent extraction behaviour of some fission product elements with N,N-dihexyl octanamide and tri-n-butyl phosphate under simulated PUREX process conditions

Extraction behaviour of some fission product contaminants like Zr(IV), RuNO(III), La(III), Ce(III) and Nd(III) with 1.1 M solutions of N,N-dihexyl octanamide (DHOA) and tri-n-butyl phosphate (TBP) in n-dodecane from nitric acid medium has been investigated under conditions prevailing in the PUREX process...

Sorption of Cs, Ni, Pb, Eu(III), Am(III), Cm, Ac(III), Tc(IV), Th, Zr, and U(IV) on MX 80 bentonite: An experimental approach to assess model uncertainty

A multi-site surface complexation/ion exchange model for dispersed MX 80 bentonite has been calibrated, considering the dissolution properties of the constituting mineral assemblage, for sorption of a large number of radionuclides, using experimental data from the present study together with well constrained literature data...
