摘要：

The acid-base equilibrium constant of the active component of the commercial extractant LIX 54, 1-phenyl-1,3-decanedione, has been determined in a water/alcohol mixed solvent (25% ethanol) at 298 K using 1.0 mol dm-3 KCl as an ionic medium. Graphical and numerical treatment of spectrophotometric data have led to the value pK(a) = 9.73 +/- 0.05. The distribution, aggregation and interactions of the reagent with other extractants used in synergistic mixtures are also discussed. A comparison of the extraction of Cu(II), Ni(II) and Zn(II) from nitrate solutions by the reagent and by mixtures of the reagent with additional ligands in toluene has been made.
