Abstract
The extraction of zinc(II) from a 1.0 mol/l hydrochloric acid solution with a mixture of neodecanoic acid diamides in toluene was studied. It is assumed that zinc(II) with a phase contact time of 5 min and CHCl = 1.0 mol/l is extracted by the anion exchange mechanism. Conductometric measurements of the molar electrical conductivity of zinc(II) extracts showed that they are electrolytes. When the phase contact time is increased to 30 minutes, zinc(II) is extracted from a solution with a concentration of HCl 1.0 mol/l in the form of a neutral complex λ = 5–10 Ohm−1 cm2 mol−1). Extractable chlorocomplexes of zinc(II) with diamide, isolated at phase contact times of 5 and 30 minutes, were characterized by IR spectroscopy and elemental analysis. Extraction of zinc(II) by mixed diamide and dihexyl sulfoxide at tcont. = 5 min showed their effectiveness
