Novel hydrophilic bistriazolyl-phenanthroline ligands with improved solubility and performance in An/Ln separations

Two novel bistriazolyl-phenanthroline (BTrzPhen) ligands, bearing benzene-sulphonate (DS-BTrzPhen) and amino-acidic (DAA-BTrzPhen) hydrophilizing moieties were developed and found to be more soluble in aqueous acidic media with improved selectivity for Am(iii) over Eu(iii) in solvent extraction stud...

Sumario:Two novel bistriazolyl-phenanthroline (BTrzPhen) ligands, bearing benzene-sulphonate (DS-BTrzPhen) and amino-acidic (DAA-BTrzPhen) hydrophilizing moieties were developed and found to be more soluble in aqueous acidic media with improved selectivity for Am(iii) over Eu(iii) in solvent extraction studies having SF(Eu/Am) values reaching >300. The remarkable activities of both ligands suggest that BTrzPhen ligands are generally still worth exploring and improving.
