structurally related glycolamide compounds were synthesised and evaluated by solvent extraction experiments for the separation of rare earth elements (REEs) from aqueous acid solutions using dodecane as the diluent. We describe herein the full synthesis of a family of bifunctional ligands with a central oxygen and focus our investigation on the effects of structural modification on the extraction efficiencies
Behaviour of the extractant Me-TODGA upon gamma irradiation: quantification of degradation compounds and individual influences on complexation and extraction
Diglycolamides (DGAs), and in particular N,N,N′,N′-tetraoctyl diglycolamide (TODGA), are well-known candidates for the co-extraction of trivalent actinides (An(III)) and lanthanides (Ln(III)) from highly acidic aqueous solutions of nuclear waste. A derivative of TODGA, the so-called Me-TODGA with the addition of a methyl-substituent on the central part of the TODGA molecule, has been proposed to improve
