Popis: Polyethyleneglycol (PEG) and its derivatives of high molecular weight, including polypropyleneglycol, were found to be used as extractants for the liquid–liquid extraction of small amounts of various metal ions. Their extraction with these extractants were studied from thiocyanate and iodide solutions. The extraction power of these extractants increased with the increasing number of ehtylene-oxide groups in PEG’s. The extractability of metal ions from their thiocyanate solution increased in the following order: Zn(II)>Mo(V)>Co(II)>Fe(III)>V(IV)>Cu(I)>Hg(II)>Cd(II)>Pb(II)>Ni(II)
