Gold(III) separation from acidic medium by aminebased ionic .
Apr 15, 2020 · The ionic liquid was used both as the hydrophobic phase and extractant in the extraction process. • The ionic liquid ([ACh][Tf 2 N]) showed the excellent separation ability for Au(III) from mixed solutions.. Anion exchange mechanism was verified by UV–vis, FTIR, 13 C NMR analysis and quantum chemical calculations. RSM was applied to predict the extraction .
