The Effect of Diluents on Extraction of Actinides and Lanthanides
- Nuclear Chemistry, Chalmers University of Technology, Kemivagen no. 4, Gothenburg, 412 96 (Sweden)
A screening experiment was carried out, where the organic phase consisted of different concentration of 2,6-bis-(5,5,8,8-tetramethyl-5,6,7,8-tetra-hydro-benzo[1,2,4]triazy-3-yl)- [2,2']bipyridinyl or CyMe{sub 4}-BTBP [1],which is the extracting molecule, dissolved in different diluents. The aqueous phase consisted of 0.01 M HNO{sub 3} and was spiked with trace amounts of {sup 241}Am and {sup 152}Eu. The ionic strength was kept constant at 1.0 M using NaNO{sub 3}. Three of the selected diluents used to dissolve CyMe{sub 4}-BTBP were abandoned: n-hexane, TPH and TBB. Another extraction experiment screened out anisole, 1,1,2,2-tetra-chloro-ethane and benzaldehyde. A kinetic experiment was then performed. In three different organic systems, three very different kinetic behaviors were observed. For a proper understanding of the kinetic mechanism, further investigations are needed. (authors)
