“…Nevertheless, conventional extractants, such as Alamine 300 and 336, can only separate Pt(IV) and Pd(II) from Rh(III) and some base metal ions, but are not effective for the extractive separation of Pt(IV) from Pd(II) [3,4], wherein the separation of Pt(IV) and Pd(II) is achieved in the following stripping process, which makes the separation process complicated and caused more secondary pollution.…”

“…This kind of the stripping phase was also used by other researchers in liquid-liquid extraction (Swain et al 2010) as well as in membrane system (Regel-Rosocka et al 2015). Swain et al (2010) studied the stripping of Pd(II) from organic phase after extraction by Alamine 300 (trioctylamine). They reported that, in the case of chloride solutions, there metal ions are stripping by a coordination-substitution reaction between thiourea (NH 2 ) 2 CS and chloride ions.…”

This work focuses on the application of polymer inclusion membrane (PIM) with tricaprylmethylammonium thiosalicylate, [A336][TS] (TOMATS), a thiol-containing task-specific ionic liquid for the transport of Pd(II) ions from aqueous solutions. 0.3 M thiourea in 0.1 M hydrochloric acid was found the most effective stripping phase in the transport of Pd(II) from membrane phase containing TOMATS. Separation of Pd(II) ions was also carried out from hydrochloric acid solution containing Pt(IV), Fe(III), Ni(II), and Mn(II). Pd(II) ions were preferably transported in the presence of these metal ions. The separation coefficients followed the order:[TS] proved to be an excellent ion carrier for Pd(II) from hydrochloric acid solution. The results also showed that transport efficiency of the PIM was reproducible and it can be useful for the development of the simple and highly effective method of Pd(II) recovery from leach liquor of spent catalysts.

“…Because the consumption of Pd increases each year, the recovery of this metal from either ores or secondary resources is essential. Several methods are used in the separation of Pd(II) from the leaching solutions of HCl or HNO 3 , such as precipitation [3], ion exchange [2,4], and solvent extraction [5][6][7][8][9][10][11][12]. Among these methods, solvent extraction is suitable for the separation of platinum group metals (PGMs) because of its high selectivity and the purity of metals thus obtained [9].…”

“…A low acid concentration is favorable for the extraction of Pd(II) with LIX 84I and PC 88A [13,14]. Most amines can extract Pd(II) with a high extraction efficiency, but the co-extraction of Pt(IV) is high, and thus the separation factor is generally low [10,15]. Third-phase formation and a low extraction percentage are drawbacks in the extraction of Pd(II) by TBP and TOPO.…”

Cyanex 301 and 5,8-diethyl-7-hydroxyldodecane-6-oxime (LIX 63) can selectively extract Pd(II) over Pt(IV) from concentrated hydrochloric acid solutions. Therefore, solvent extraction experiments have been performed by extractant mixtures containing either Cyanex 301 or LIX 63, and the extraction behavior of Pd(II) was compared. Among the mixtures of Cyanex 301, the highest synergistic enhancement coefficient was achieved by mixing Cyanex 301 and trioctylphosphine oxide (TOPO). However, it was very difficult to strip the Pd(II) from the loaded mixture phase. Among the mixtures of LIX 63, the mixture of LIX 63 and alamine 336/TOPO enhanced the extraction of Pd(II). Although the synergistic coefficient by Cyanex 301 + TOPO was higher than that by LIX 63 + Alamine 336, the Pd(II) in the loaded mixture phase of LIX 63 and alamine 336 was easily stripped by thiourea.
