Extraction of inorganic and organic substances from aqueous solutions as host-guest complexes by vaseline oil containing crown compounds

Abstract

Extraction of some metal ions and biologically active organic compounds as host-guest complexes from aqueous phase by solutions of crown compounds in Vaseline oil was studied. The same extraction systems were studied using the extractant as a constituent of a carbon paste electrode. The conditions ensuring the maximum extraction capability of Vaseline oil in the presence and absence of crown compound were found. © 1996 MAEe cyrillic signK Hayκa/Interperiodica Publishing.
