| Abstract: | The synergic extraction of magnesium, calcium, strongium, barium and lithium into cyclohexane or benzene containing 1-phenyl-3-methyl-4-acyl-pyrazol-5-one (HA) and tri-n-octylphosphine oxide (TOPO) was investigated as a function of pH, HA and TOPO concentration. The extracted species when the 4-benzoyl compound was used, were MA2(TOPO)2 (M = Mg, Ca, Sr), BaA2(TOPO)3 and LiA(TOPO)2. When the 4-trifluoro-acetyl derivatives was used, the extracted species were the same except for SrA2(TOPO)3. Extraction constants for the synergic extractions were calculated. |
