Solvent extraction studies of indium-mixed chelates with β-diketones in benzene media

Abstract

Mixed chelate formation of indium with several β-diketones has been studied from benzene media. The extraction of indium by BFA and FFA has been carried out as a function of pH and concentration of the ligand to ascertain the nature of the complexes. The extraction of indium by a mixture of β-diketones, viz., BFA-BA, BFA-DBM, FFA-BA, FFA-DBM, FFA-BFA and DBM-BA has also been studied as a function of the solution parameters. The nature of the mixed complexes formed as well as their equilibrium constants, statistical and stabilisation constants have been evaluated.
