“…Extractants, such as TOA (tri-n-octylamine), [40][41][42] Aliquat 336, 43) and n-octylaniline [44][45][46] were used for the extraction of In from different types acid medium. In the solvent extraction of indium from concentrated hydrochloric acid solution by basic extractants, extraction of neutral adduct or exchange of anionic indium species can be occurred depending on the acidity of the aqueous solution 41)…”

AbstractIndium is one of the rare metals, and it has been used mainly for preparation of indium tin oxide (ITO). This review investigated the process parameters and the merits and demerits of several methods to recover indium from the leaching solution of secondary resources, such as solvent extraction, ion exchange, and precipitation. D2EHPA has been used mostly as a cationic extractant for indium extraction in moderate acid solutions, while amine extractants are used in strong hydrochloric acid solution. Since the loading capacity of resins for indium is generally small, ion exchange has some advantage over solvent extraction only when the concentration of indium is low.

The extraction behaviors of strontium from nitric acid solution were investigated with N,N,N ' ,N ' -tetraisobutyl diglycolamide (TiBDGA). Effects of acidity, diluents, concentration of extractant and temperature on the distribution ratio of strontium (D Sr ) were examined. The stoichiometry of the extracted molecule was Sr 2+ :TiBDGA of 1:3. The apparent extraction equilibrium concentration constant logK ex was 3.25. The enthalpy change ǻH and entropy change ǻS were -55.6 kJ mol -1 and -124 J mol -1 K -1 , respectively. The extraction is an exothermic process. Through two strip stages, strontium could be stripped effectively by 0.01 M nitric acid solution.

“…Indium, a rare and valuable metal [1][2][3], is an important element which is used in the field of electronics [4], energy-related industries [5] and making low melting alloy [6]. Indium has no its own minerals so it has to be recovered as a byproduct from other metallurgical processes [1], together with zinc, lead, copper and tin [6]. Solvent extraction is a commonly used method for the purification of indium from the zinc hydrometallurgical process [4,7,8].…”

Experiments were performed in an interdigital micromixer with 30 microchannels (40 μm width of each channel) to separate In3+, Fe3+and Zn2+from sulfate solutions using Di-(2-ethylhexyl)phosphoric acid (D2EHPA) as the extractant. The effects of pH, extractant concentration and flow rate on the extraction efficiency and flow rate on mass transfer coefficient of In3+, Fe3+and Zn2+were investigated. At a phase flow rate of 7.0 mL/min and initial solution pH of 0.423, the extraction efficiency of In3+, Fe3+and Zn2+was 99.29%, 3.43% and 2.54%, respectively and mass transfer coefficient of In3+, Fe3+and Zn2+was 144.307 s−1, 1.018 s−1and 0.750 s−1. Then, the loaded organic phase was stripped in an interdigital micromixer. At a phase flow rate of 9.0 mL/min and HCl concentration of 160 g/L, stripping efficiency of In3+was 98.92% and mass transfer coefficient of In3+was 169.808 s−1, while concentration of Fe3+and Zn2+was lower than 0.005 g/L with good separation of In3+from Fe3+and Zn2+.
