Popis: | The complexation and extraction properties of RC(S)NHP(X)(OiPr)2 [X = S, R = PhNH (HLI); X = O, R = PhNH (HLII), Ph (HLIII)] towards cobalt cations were studied. The nitrocellulose membrane was used as a carrier for HLI−III. The maximal degree of extraction of cobalt cations from an aqueous solution is observed at pH = 7.8–8.4. It was established that complexes formed are kept in a water solution on a surface of the carrier and washed away in 96% aqueous ethanol. The membrane modified by HLI allows extraction and concentration of Co(II) selectively, while the modification by HLIII leads to the selective extraction of Co(III). |
