“…Traditionally, the hydrometallurgical recovery of PGMs is based on solvent extraction processes based on the fact that noble metal ions can easily form species which are extractable into the organic phase with various reagents [3,4]. Many different extractants have been studied and proposed, including dialkyl sulphides and sulphoxides [5][6][7][8], alkyl derivatives of 8-hydroxyquinoline [9], hydroxyoximes and ketoximes [10][11][12][13][14][15], hydrophobic amines and quaternary ammonium salts [16][17][18][19][20][21], organophosphorus extractants [22][23][24][25][26] and pyridinecarboxamides [27,28].…”

“…Very short times (about few minutes) neccesary to achieve the extraction equilibrium are a huge advantage of reagent [PIP16]Cl in comparision with commercial dialkyl sulfides. Kinetics of palladium(II) extraction from acidic chloride solutions with these extractants is very slow and a few hours are needed to achieve equilibrium [38][39][40]. Pyridine derivatives like pyridinecarboxamides also extract palladium(II) very fast and efficiently.…”
