摘要：

Complexation processes that occur when hexacyanoferrate(II) immobilized in gelatin is brought into contact with aqueous solutions of dithiooxamide at pH 12 are studied. Unlike the binary metal ion-dithiooxamide systems studied so far, the final product in this case was Pb(II) sulfide, rather than the Pb(II) complex with the indicated ligand. Concentration of Pb(II) sulfide was shown to depend on dithiooxamide conc centration in a solution in contact with the matrix. A scheme for the complexation process is proposed.
