Description

The extraction of radium and barium into a mixture of 1-phenyl-3-methyl-4-benzoylpyrazol-5-one /HPy/ and trioctylphosphine oxide /TOPO/ in n-hexane or cyclohexane was investigated as a function of pH and TOPO concentration. It was found that the synergistic enhancement of the extraction is caused by the formation of mixed complexes of type M/Py/2/TOPO/3 and the overall extraction constants of both complexes were calculated.
