Usually extractants have been used as solution in diluents. Diluent influences on properties of extraction mixture very significantly. Hydrocarbons are traditional diluents. Unfortunately, hydrocarbons are low-polar compounds and therefore are not good as diluents for polar extractants.
Fluorinated diluents are possible alternative for hydrocarbons ones. Best studied polar fluorinated...
The separation of uranium(VI) and plutonium(IV) by solvent extraction from spent nuclear fuels has already been studied with several families of extractants such as trialkyl phosphate, phosphine oxides or monoamides. A new family of extractant containing the carbamide function (also called urea with the general formula R1R2NC(O)NR3R4) is currently studied in our laboratory. Only few...
Lutetium-177 (177Lu) is a radionuclide with tremendous potential in radionuclide therapy. 177Lu based pharmaceuticals are applied in neuroendocrine tumour treatment and have been approved for prostate cancer treatment. We have proposed the idea of a 177mLu/177Lu radionuclide generator for 177Lu production based on the separation of the daughter...
N,N'-dimethyl,N,N'-dioctylhexylethoxymalonamide (DMDOHEMA) is used to separate An(III) and Ln(III) from fission products in several liquid-liquid extraction processes (DIAMEX, EXAm, GANEX)$^{1-2}$ that aim at recycling actinides. One key to understand these processes is the stoichiometry of the complexes formed during extraction. Time-resolved laser fluorescence spectroscopy (TRLFS) poses, in...
