Electron Microscopical Study of Lead(II) Sulfide Implanted into a Glassy Biopolymer Matrix

Abstract—Thin-layer glassy biopolymer matrix implants obtained as a result of the contact of lead(II) hexacyanoferrate(II) Pb₂[Fe(CN)₆] with an aqueous alkaline solution of ethanedithioamide (dithiooxamide) H₂N—C(=S)—C(=S)—NH₂ have been studied by high-resolution scanning electron microscopy. It is shown that lead (II) sulfide PbS nanoparticles with sizes of up to 50 nm are formed in accordance with the theoretical hypotheses.
