“…In addition, the extraction selectivity of EHTG was compared with that of DDT. DDT could not be carried out at pH eq higher than 3 because of the precipitation of Ga(OH) 3 . As seen from Figure 2 (a), the extraction order for the metals with EHTG was Cu(II)>In(III)>Ga(III)>Zn(II), while Al (III) was not extracted with EHGT.…”

“…Toward the development of recovery techniques of In(III) and Ga(III), a variety of extractants such as organic phosphoric acids [2][3][4][5][6][7][8][9], amines [10,11], carboxylic acids [12] and oximes [6,12,13] have been actively studied for the selective extraction of In (III) and Ga (III). Gupta et al reported that In (III) and Ga (III) were qualitative extracted at hydrochloric acid concentrations of over 0.01 M(= mol dm -3 ) and 1 M hydrochloric acids, respectively when Cyanex 923 in toluene was used [14].…”

Extraction selectivity of In (III) and Ga (III) was investigated using 2-ethylhexyl thioglycolate (EHTG) with a thiol group and an oxygen atom to recover these metals from zinc refinery residue and waste solar panels. The extraction order with EHTG was Cu(II)>In(III)>Ga(III)>Zn(II), while Al (III) was hardly extracted at all. While In(III) and Ga(III) were not extracted at all with 1-dodecanethiol (DDT) with contains only a thiol group although Zn (II) and Cu (II) were extracted. This indicates that the oxygen atom in the EHTG ester plays an important role in the extraction of these metals. The mutual separation of In(III), Ga(III), Zn(II) and Cu(II) is possible in almost one step with EHTG. The extraction equilibria of In(III) and Ga(III) with EHTG are also discussed. Furthermore, the stripping of In(III) and Ga(III) extracted into the organic phase was achieved using appropriate concentrations of NaOH and acids.

“…Preliminary experiments were performed using the single component solution at a concentration of 100 ppm of metal ions, and the pH was controlled at the optimum pH for selective separation established in previous batch experiments. Eluant solutions of HCl, HNO 3 and H 2 SO 4 were used for the recovery of metal ions from the resin. All the experiments were carried out at ambient room temperature (25±1 o C).…”

“…In the near future, a significant increase in indium demand is expected because of its use in many new technologies. Indium is used in the field of electronics for semiconductor devices, thermistors and optical devices, electronic soldering (alloys); in the nuclear field it is being used for control rods in reactors; indium is also used to improve some dental alloys [2,3]. Cyclotron-produced 111 In is widely used in nuclear medicines for labeling blood cell elements and monoclonal antibodies.…”

Chromatographic separation of In(III) from Cd(II) in aqueous solutions using commercial resin (Dowex 50W-X8)

This work assesses the potential of an adsorptive material, Dowex 50w-x8, for the separation of indium ions from cadmium ions in aqueous media. The adsorption behavior of Dowex 50 w-x8 for indium and cadmium ions was investigated. The effect of pH, initial concentration of metal ions, the weight of resins, and contact time on the sorption of each of the metal ions were determined. It was found that the adsorption percentage of the indium ions was more than 99% at pH 4.0. The result shows that In (III) was most strongly extracted, while Cd(II) was slightly extracted at this pH value. The recovery of In(III) and Cd(II) ions is around 98% using hydrochloric acid as the best eluent.

Der Bedarf an Indium steigt mit dem Wachstum der Elektronikbranche, in der es vorwiegend eingesetzt wird. Daher wurde anhand einer Modelllösung, die in ihrer wesentlichen Zusammensetzung dem Erz Sphalerit entsprach, ein mehrstufiges Extraktionsverfahren zur Gewinnung von Indium entwickelt. Die ursprünglich sehr niedrige Indiumkonzentration in der Lösung wurde durch mehrere aufeinanderfolgende Extraktions‐ und Reextraktionsschritte deutlich erhöht. Das vorgestellte Verfahren zeichnet sich durch einen geringen Chemikalienbedarf und eine hohe Reinheit des gewonnenen Indiumoxids aus.
