A series of ionic liquids consisting of anilinium cations with varying alkyl chains and metallic (Sb and Bi) halides as anions have been synthesized and thoroughly characterized by using multinuclear (1H and 13C) NMR, FT-IR, Raman and XPS techniques. They have been exploited as adsorbents for the dy...
