Determination of actinides in radioactive waste after separation on a single DGA resin column

Extraction of Np(IV/VI) from nitric acid medium using three different tripodal diglycolamide ligands in ionic liquid: Batch extraction, spectroscopic and electrochemical investigations

“…Out of the various ligands employed for Np separation from acidic feeds, those involving diglycolamides (DGA) have been found to be quite efficient [14,[18][19][20][21][22][23][24]. In a subsequent development, multiple-DGA ligands were found to be significantly more promising than the commonly employed simple DGA ligands such as TODGA (N,N,N',N'-tetra-n-octyl diglycolamide).…”

Improving the Elution Rate of Extraction Chromatography on the Purification of Americium

“…Well logging for underground oil and gas exploration(LANL LA-UR-16-24374)GOALSManipulate resin size and porosity to obtain an optimal configuration to improve elution rate without adverse effect on separation  Effects of resin size and porosity on flow can be easily tested  Test flow rates through various resin specs  Combine optimal specs to establish increased flow rate  Larger resin shown to increase flow rates in non-actinide separations1,2,9 …”
