摘要
Complexation processes that occur between cadmium(II) hexacyanoferrate(II) (Cd-2[Fe(CN)(6)]) and 3d-metal ions M(II) (M=Mn, Co, Ni, Cu, Zn) in thin gelatin layers with the immobilized cadmium(II) hexacyanoferrates when brought in contact with aqueous solutions of d-metal chlorides are studied. Cd2+ ions were found to be replaced to some extent by M2+ ions of the indicated d metals (except for Mn(II)) and form binuclear (dd)-metal hexacyanoferrates(II). A complete replacement of Cd(II) and formation of M-2[Fe(CN)(6)] was observed in none of the cases.
