Abstract

Thiosalicylate anions are known for their complexing capacity towards a wide range of transition metals. We have used this important sulfur-containing anion to synthesize the task-specific ionic liquid dioctylimidazolium thiosalicylate [DOIM] [TS] via ion exchange method in two steps. For characterization of [DOIM] [TS] we have used, electron spray ionization mass spectroscopy (ESIMS), nuclear magnetic resonance (NMR), infrared spectroscopy (IR), and thermal gravimetric analysis (TGA). The sulfur-containing IL was investigated for the removal of heavy metals (Cr³⁺, Mn²⁺, Fe²⁺, Co²⁺, Ni²⁺, Cu²⁺) from their aqueous solutions. The extraction efficiencies were determined through atomic absorption spectroscopy.
