Селективное определение оксида свинца(II) во фториде свинца(II)

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.
