“…[8,16,[23][24][25] Room temperature Ionic liquids, ILs, present a series of unique properties such as low volatility, low toxicity, high solubility for metals combined with tunable hydrophobicity. [26][27][28][29] All these aspects make them appealing for many applications such as catalysts, [30] environmental contaminants removal systems, [31,32] electrolytes for energy storage devices, [33][34][35][36] and extracting agents. [37][38][39][40][41] Although recently many strategies have been reported to implement metals recovery and separation, such as membrane separation, ion imprinted polymers, solid phase adsorption, [42][43][44] liquid-liquid extraction is still appealing due to its robustness, ease of implementation, and scalability, making it exploited also at industrial scale.…”
