Recovery of actinides and lanthanides from high-level liquid waste by extraction chromatography using TODGA+TBP impregnated resins

A 30% (w/w) N,N,N′,N′-tetraoctyldiglycol amide (TODGA) and 10% (w/w) tributyl-phosphate (TBP)-containing resin was prepared and the batch uptake of several actinides [U(VI), Th(IV), Am(III), Cm(III), Cf(III)] and selected fission products from nitric acid solutions was investigated...

Separation of actinides by extraction chromatography prior to X-ray fluorescence measurement for analytical control of a PUREX test

Five separation methods by Eichrom column extraction chromatography were developed and implemented for performance control of a PUREX (Plutonium, Uranium Refining by EXtraction) test.

Four of them, concerning the separation between actinides, are described in this work...
