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

Extraction of some metal ions (Ni(II), Co(II), Cu(II), and Pb(II)) and biologically active organic compounds (Karbation (sodium N-methyldithiocarbamate), thiourea, Prefiks (2,6-dichlorothiobenzamide), and Ioksinil (4-hydroxy-3,5-diiodobenzonitrile)) 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
