Sorption of lead(II) on very poorly soluble hexacyanoferrates(II) of transition metals: CuII, NiII, ZnII, CoII and on the ion-exchange composite obtained by mixing of nickel(II)-potassium hexacyanoferrate(II) with sulfonated phenolic resin serving as matrix was studied. Sorption was performed from solutions of hydrochloric acid at concentrations ranging from 10-4 to 10-1mol. dm-3. Analytical distribution coefficients for lead(II) sorption on these adsorbents were determined. Lead(II) sorption on Dowex 50 and the composite resin was studied as well.
