On the Dissolution of Metals in Ionic Liquids 1. Iron, Cobalt, Nickel, Copper, and Zinc

Abstract

Ionic liquids are critical reagents for science and technical processes nowadays. Metals are the most used reagents in the industry. It is crucial to have a deeper understanding of how ionic liquids and metals could interact. In this article the interaction of those two families of compounds is accessed. The dissolution (reaction) of metals with ionic liquids is studied, namely the influence of temperature, redox potential, and availability of an oxidant in the process. The final state achieved by the iron metal samples was also addressed by Mössbauer spectroscopy.

“…71 Recently, Vicente et al studied the “dissolution” of bulk Fe, Cu, Ni, Co, and Zn in [BMIM]Cl, and concluded that the dissolution happened through oxidation to soluble salts. 72 Similarly, there are many examples of polynuclear metal clusters within IL matrices 73 —for example, elemental bismuth and bismuth( iii ) cations synproportionate in the ionic liquid [BMIM]Cl/AlCl 3 within minutes to form bismuth polycations (such as Bi 5 (AlCl 4 ) 3 ) in situ . 74 While there is a vast body of work on Cu NPs in water as potential antimicrobial species, very little of it is relevant to TAPILs, where copper speciation is understudied.…”
