The possibility of use of acetylacetone to selective separation the lead (II) oxide from lead (II) fluoride was investigated. Were рroposed to use mixture of acetone, acetylacetone and Triton X-100 for dissolving PbO. Were chosen the optimum concentration of the reactants and selective dissolution conditions allowing quantitatively retrieve lead (II) oxide at minimum solubility of lead(II) fluoride. A complexonometric techniques for determining 0.3-3% PbO in the mixture with PbF₂ were developed.

Key words: lead(II) oxide, lead(II) fluoride, acetylacetone, triton X-100, selective dissolution
