Lead sulfide nanopowders have been prepared from aqueous solutions of lead acetate and sodium sulfide in the presence of sodium ethylenediaminetetraacetate or citrate. From microscopy and X-ray diffraction data purity and size of the formed nanoparticles are determined by the reagents concentrations, presence and nature of the complexing ligand, and the ratio of lead ions concentration to that of the ligand. PbS nanoparticles of the predefined size ranged from 5 to 55 nm can be prepared by controlled hydrochemical precipitation.
