Abstract
Abstract The synthesis of a new Schiff base ligand (HL) formed by the condensation of salicylaldehyde with 4′-amino-4,10-diaza-4,10-ditosylbenzo-12-crown-4 is described. The complexation of this ligand with Ni(II), Cd(II), Cu(II), Co(II) and UO2(VI) was investigated by potentiometric titration. The results indicate that Cu(II), Ni(II), Co(II). Cd(II), UO2(VI) give complexes with the metal-ligand ratio of 1:1. The order of the formation constants of the mononuclear complexes is Ni(II) > Cd(II) > Cu(II) > Co(II) > UO2(VI).
