Solvent extraction of alkaline earths with 1-phenyl-3-methyl-4-stearoylpyrazol-5-one and TOPO
Description
The synergic extraction of Ca, Sr, and Ba ions from aqueous solutions into cyclohexane or benzene containing 1-phenyl-3-methyl-4-stearoylpyrazol-5-one (HPMSP) and TOPO has been studied. Quantitative extraction (log D>2) was attained at pH>5.4 for Ca, pH>6.5 for Sr, and pH>7.3 for Ba when cyclohexane containing 0.05 M HPMSP and 0.01 M TOPO was used, and the corresponding values for benzene were 6.5, 7.8, and 8.4. Extracted species were M(PMSP)2(TOPO)3 (M=Ca, Sr, Ba) for cyclohexane and Ca(PMSP)2(TOPO)3 and Sr(or Ba) (PMSP)2(TOPO)2 for benzene
