Transport of Ag(I), Cd(II), Co(II), Cu(II), Ni(II), Pb(II) and Zn(II) cations across a bulk liquid membrane containing N,N0-dibenzyl-N00-(2,2,2-trifluoroacetyl)-phosphoric triamide as a new carrier is studied by atomic absorption spectrometry. The results show selective and efficient transport of the copper(II) cation from aqueous solution in the presence of the other cations. Various factors are optimized in order to obtain maximum transport efficiency. The PTC ligand is characterized by single crystal X-ray diffraction analysis, IR, NMR (19F, ..31P, 1H, 13C) and mass spectroscopy. The complex for mation reaction between copper(II) and PTC is studied by a conductometric method, which shows the 1 : 1 stoichiometry for ligand and copper(II).
