Extraction of actinides using N, N, N′, N′-tetraoctyl diglycolamide (TODGA): a thermodynamic study

The effect of temperature on the extraction behaviour of Am(III), Pu(IV) and U(VI) from nitric acid medium was studied employing N,N,N′,N′-tetraoctyl diglycolamide (TODGA) in n-dodecane...

Keywords: TODGA, Actinides, Thermodynamics, Extraction constant

N,N,N′,N′-tetraoctyl-3-oxapentane-1,5-diamide impregnated magnetic particles for the uptake of lanthanides and actinides from nuclear waste streams

A novel, simple technique based on magnetically assisted chemical separation (MACS) has been developed for the uptake of lanthanides and actinides from pure nitric acid solutions as well as from Simulated Pressurized Heavy Water Reactor-High Level Waste (PHWR-SHLW)...

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...
