Investigation on Gold Dissolution Performance and Mechanism in Imidazolium Cyanate Ionic Liquids.

ABSTRACT: To explore green gold leaching reagents, a series of imidazolium cyanate ionic liquids (ILs), 1-ethyl-3-methyl-imidazolium cyanate ([C₂MIM][OCN]), 1-propyl-3-methyl-imidazolium cyanate ([C₃MIM][OCN]) and 1-butyl-3-methyl-imidazolcyanate ([C₄MIM][OCN]) were synthesized and characterized by Nuclear Magnetic Resonance (NMR), Fourier Transform Infrared Spectroscopy (FTIR) and thermogravimetric (TG) analysis. In this research, the imidazolium cyanates were utilized as a solute, which not only decreased the usage of ILs but also increased their gold dissolution capability. The gold dissolution performances of three imidazolium cyanates were characterized by dynamic leaching test and Scanning Electron Microscopy (SEM). The results show that the all three imidazoli
