“…Di(2ethylhexyl)phosphoric acid (D2EHPA or P204) [37,38], hexyl phosphonic acid mono-2-ethyl-hexyl ester (P507 or PC88A) [39], Bis(2,4,4-trimethylpentyl)phosphinic acid (Cyanex272) [40] were most widely used, the three extraction solvent acid decreased gradually enhanced the ability of separation of cobalt and nickel in turn. D2EHPA can extract many metallic cations from various Carboxylates [41], Citrate [42][43][44], chloride [37,38,45], nitric [46,47], and sulfate [48][49][50]solutions. After the first commercial process using D2EHPA, P507 was developed and widely used in base-metal solvent extraction [39].…”

Two interesting compounds such as quaternary ammonium lignin(QAL) and 2-ethylhexyl phosphoric acid mono-2-ethylhexyl ester (P507) were synthesized as ionic liquids(QP-ILs) for the extraction of metal ions. The extraction behavior of Co(II) and Ni(II) from chloride solution was compared between QP-ILs and P507. The results showed that the extraction rates of Co(II) and Ni(II) in the two solutions varied with the extraction conditions, but QP-ILs has stronger extractability for cobalt than P507, while Ni is on the contrary. Under the same conditions, the Co/Ni separation performance(βCo/Ni) in QP-ILs is superior to that in p507. At pH4.0, 55℃, concentration of 20%, extraction time of 10 minutes, the βCo/Ni of QP-ILs reached to 2703, while that of P507 was only 164. In conclusion, QP-ILs was more efficient than P507 for separating Co from mixed solutions.
