Selective solvent extraction of tetrahedrally-coordinating transition metal ions from acidic aqueous media using benzimidazole–phosphinate ligands: specificity for zinc(II) over copper(II)
New Journal of Chemistry Pub Date: DOI: 10.1039/A903534F
Abstract
The synthesis, solution complexation behaviour and solvent extraction ability of related chelating mono-and bis-(benzimidazole)phosphinate ligands 8 and 9 has been assessed. 31P NMR, fluorescence and absorption spectroscopy and electrospray mass spectrometry revealed preferential formation of 1:1 complexes with the divalent ions Zn, Co and Ni, and ML2 complex formation with the bidentate ligand. Extraction studies showed that 9 extracted Zn>CoNi with no extraction of copper(II), but avid extraction of copper(I), generated insitu, consistent with the ligand's preference for the binding of tetrahedrally-coordinating metal ions.
