Abstract
The extraction processes of indium(III) from media of various complexing
ability, chloride and nitrate, in toluene or chloroform, have been elucidated.
Indium is extracted from 1 M nitrate medium as In(PBI)3 with HPBI alone
and as In(PBI)3(TOPO)2 with TOPO-HPBI mixtures, while it is extracted
from 1 M chloride medium as In(PBI)3 and InClx(PBI)3-x(TOPO)2.
The complexation of In in the aqueous phases, the extraction of nitric acid
and various solute-solute and solute-diluent interactions in the organic
phases must be taken into account in the processes. The results are compared
with those obtained previously with 1-phenyl-3-methyl-4-benzoyl-pyrazol-5-one
under the same conditions.
