Adsorption Behavior of Vanadium Using Supported 1-Butyl-3-Methylimidazolium Chloride Ionic Liquid

Yu Liang, Shenxu Bao, Yimin Zhang, Bo Chen & Chen Yu
Imidazole-based ionic liquid 1-Butyl-3-methylimidazolium chloride was immobilized on polymer support by chemical grafting and utilized to separate vanadium (V) from a vanadium-containing solution. Characterizations with elementary analysis, Fourier transform infrared (FTIR), 13C nuclear magnetic resonance (NMR), scanning electron microscopy (SEM) and energy dispersive spectrometer (EDS) proved the successful loading of the ionic liquid on the surface of the support. The adsorption capacity toward V(V) reached 222.42 mg/g under experimental conditions, which was significantly higher than...
