“…Keeping in mind that the apparent coordination numbers of indium in these complexes are uncommonly high, it is probable that in InL 3 (TOPO) 2 The extraction with single component HPBI or HPMBP from nitrate medium is better than from chloride medium, due to the indium complexation by the latter anion in the aqueous phase. On the contrary, in the presence of TOPO, since only InL 3 (TOPO) 2 is extracted from nitrate medium, while all four InCl x L 3 -x ( TO P O ) 2 lipophilic complexes are extracted, the extraction is much more efficient in the latter case.…”

“…It agrees with the In-O bond being stronger than the In-Cl one in mixed complexes, according to the general trend. Therefore, the stability of mixed InCl x L 3 -x ( TO P O ) 2 complexes should decrease with x, as should do their lipophilicities, and hence the corresponding extraction constant. This is true from K 6 to K 8 .…”

“…To explicit this process, in a first step, approximate concentrations of I n L 3 ( TO P O ) 2 In a second step, since the extraction of InCl 2 ( P B I ) (TOPO) 2 is favoured for low initial concentrations of HPBI, it was assumed that this species was the only extracted species for [HPBI] i, org = 0.01 M and [TOPO] i, or g = 0.01 M (curve 6a), 0.02 M and 0.04 M (curves not presented). Thus, logK 7 was calculated according to this assumption for the corresponding experimental points.…”

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 I n ( P B I ) 3 ( TO P O ) 2 with TO P O -H P B I mixtures, while it is extracted from 1 M chloride medium as In(PBI) 3 a n d InCl x (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.

Remediation of copper ions from aqueous solution using hybrid magadiite: kinetics, isotherm and mechanism of removal

et al. 2018

This paper deals with the potential use of hybrid magadiite composite as an alternative adsorbent for the removal of copper ions. Na-magadiite was synthesized by the hydrothermal method. The hybrid magadiite was prepared by using pyrazolone as an organic ligand via dry impregnation technique from Na-magadiite. The hybrid magadiite composite is used in the removal of copper ions in sulphate media. The presence of an organic molecule in hybride magadiite is verified by thermogravimetric analysis and infrared spectroscopy. The X-ray diffraction pattern illustrates the intercalation of the organic ligand into Na-magadiite interlayers and the preservation of the structure after intercalation. The scanning electron micrograph images of modified Na-magadiite show the expansion of the basal spacing resulted in a breakup of the spherical nodules and the concomitant parallel arrangement of the platelets. In batch experiments, the influence of reaction time, kinetics, pH and the initial concentration of copper(II) were investigated. In the case of modified Na-magadiite, the kinetic model of extraction adapted is pseudo-second order. The metallic cation was extracted at a very low pH 1.9, and the capacity obtained is 330 mmol/kg, the complex formed is of the CuL 2 type.
