“…Organic phases were prepared by diluting the extractants with kerosene (Daejung Co., Shiheung, Korea, >90%). Ionic liquid, IL ALi-D2, was synthesized by mixing an equimolar concentration of Aliquat 336 (R 4 NCl, BASF Co., Ludwigshafen, Germany, 93%) and D2EHPA (HA) (Daihachi Chemicals, Osaka, Japan, 95%) as reported in the literature [16,18]. A sufficient amount of NaHCO 3 (Daejung Co., Shiheung, Korea, 99%) was added to the mixture to promote the formation of IL ALi-D2.…”

“…This can be ascribed to the extraction of hydrogen ions by IL, leading to an increase in pH eq , and thus extraction percentage was greatly improved. The extraction reaction of Co(II) and hydrogen ions by IL ALi-D2 can be expressed as Equations ( 3) and ( 4) [18]. Emulsion formation was also observed during the extraction at pH 4 and 5, which can be ascribed to an amphiphilic behavior of component ions.…”

“…Some advantages of the above-mentioned ILs are good extractability, efficient separation, high recovery, and environmental friendliness [14,18]. The dual function of synthesized ILs has also been noted in recent studies because these synthesized ILs not only show good separation of metals but also extraction of hydrogen ions which contribute to control solution pH, resulting in favorable extraction [3,18]. These ILs can extract metal species by either ion exchange or ion pair mechanism [15,19].…”

“…Instead of mixing some extractants, synthesis of some kinds of task specific ionic liquids (ILs) is regarded as a means to achieve synergistic extraction [11,12]. In particular, the synthesized ILs derivated from commercial extractants such as Aliquat 336 (N-Methyl-N,N,N-trioctylammonium chloride) or Cyphos IL (phosphonium ionic liquid) have been employed for the extraction and separation of metals [11][12][13][14][15][16][17][18]. Some advantages of the above-mentioned ILs are good extractability, efficient separation, high recovery, and environmental friendliness [14,18].…”

The development of extraction systems to improve the extraction efficiency of metals using commercial extractants and ionic liquids is of importance. The extraction behavior of Co(II) between mixture of Alamine 336/Aliquat 336 and D2EHPA and synthesized ionic liquid ALi-D2 was compared in this work. Some factors, such as equilibrium pH, properties of the extractants, and concentration of components in the mixture had a remarkable effect on the extraction of Co(II). The interactions occurring in the mixtures as well as the change in solution pH were analyzed. Co(II) was completely extracted by ionic liquid when equilibrium pH was higher than 6.5, while it was difficult to extract Co(II) by employing the mixture of D2EHPA and Alamine 336/Aliquat 336. The formation of ionic liquid in the mixture of D2EHPA and Aliquat 336 was verified through FT-IR spectra. In addition, the competition extraction of hydrogen ion and Co(II) by ionic liquid ALi-D2 was explained. Among the three kinds of extractants, the ionic liquid showed the best extraction efficiency for Co(II) and pH control from weak acidic solutions. The present study provides valuable information on the extraction behavior of metal ion by the mixtures of commercial extractants, and thus can give some light on the development of metal extraction systems.

The objective of this study is to develop ionic liquids (ILs) derived from organophosphorus acids, featuring thermomorphic phase behavior tailored for homogeneous liquid–liquid extraction applications, addressing the challenges posed by the high viscosity of ILs. The novelty of our work includes a logP‐based guideline for designing thermomorphic water/organophosphorus IL solvent systems and a proof‐of‐concept study on homogeneous liquid–liquid extraction applications. Specifically, we reported a series of novel ILs exhibiting lower critical solution temperature behavior in aqueous solutions by exploring various combinations of tetraalkylammonium cations with organophosphorus acid‐based anions. Practical applications utilizing this type of thermomorphic solvent system for extracting metal ions and acids were demonstrated. The benefits of homogeneous extraction, as well as the limitations stemming from the salting‐out effect, were presented and discussed.

BACKGROUND Cobalt, nickel and lithium are crucial in the manufacture of batteries. Therefore, the recovery of these metals from spent lithium ion batteries (LIBs) has attracted much attention because of their benefits in terms of economics and the environment. RESULTS In the present work, the recovery of metals such as cobalt, nickel, manganese and lithium from synthetic sulfuric acid leaching solutions of spent LIBs was performed by solvent extraction using synthetic ionic liquids (ILs) and a mixture of Cyanex 301 and Alamine 336. First, cobalt was selectively extracted over other metal ions by extraction with IL(ALi‐SCN). The role of SCN− during the extraction was also investigated, and the extraction reactions of cobalt by both ALi‐SCN and Aliquat 336 were verified. The cobalt in the loaded ALi‐SCN was stripped by ammonia solution. After adjusting the raffinate pH, extraction with the mixture of Cyanex 301 and Alamine 336 selectively extracted nickel over manganese and lithium. The extracted nickel was completely stripped by 75% aqua regia. Manganese was selectively extracted by IL(ALi‐CY) after adjusting the pH of the raffinate. The manganese in the loaded ALi‐CY was stripped by HCl solutions. Therefore, three‐step solvent extraction resulted in a raffinate containing only lithium. CONCLUSIONS A process was proposed to separate Co(II), Ni(II) and Mn(II) from the sulfuric acid solutions of spent LIBs. The mass balance of continuous experiments indicated that the purity of the stripping solution of Co(II) and Mn(II) was higher than 99.9%. © 2020 Society of Chemical Industry
