Synergistic extraction of copper(II) and zinc(II) with 1-phenyl-3-methyl-4-benzoyl-5-pyrazolone and tri-<i>n</i>-butyl phosphate by two-phase <i>p</i>H titration
108-110The extraction of Cu(II) and Zn(II) with 1-phenyl-3-
methyl-4-benzoyl-5-pyrazolone (PMBP) and tri-n-butyl
phosphate(TPB) in benzene has been studied by
two-phase pH titration. The formation constants of
the extracted complexes have been computed with
computer program SCTPT. The effects of pH and nature
of extractants on the extraction have been investigated
