Study of solid extractants based on malonamides, diglycolamides, and bipyridines for the partitioning of minor actinides from high active wastes

Radiochemistry

“…Radioisotopes from the nuclear industry are usually dissolved in nitric acid solution and specific polymers and resins 245 have been developed to extract specific elements, such as strontium, 246 plutonium or americium 247 or groups of elements such as the actinides. 248 In the latter case a distinct improvement 249 in efficiency can be made by the use of supercritical carbon dioxide. Fission palladium can be removed 250 from nuclear waste using electrodeposition in an ionic liquid (1-butyl-3-methylimidazolium chloride).…”

A Novel Extraction Chromatography Resin for Trivalent Actinides Using 2,6-bis(5,6-diisobutyl-1,2,4-triazine-3-yl)pyridine

“…The higher stability of the isobutyl-BTP compared to other BTP extractants, and the stability of its tridentate complexes made it a promising candidate for extraction chromatography resins (11). Sulakova et al have shown that the backbone used can influence the extraction behavior of chromatography resins (17). In comparisons made by Sulakova et al on TODGA resins, the extraction behavior of europium was different by orders of magnitude depending on the resin backbone ( Fig.…”
