Abstract

The task specific ionic liquid tricaprylmethyl ammonium thiosalicylate proved to be an excellent extraction agent for chromium from aqueous solution. Chromium was removed from tannery effluents to a greater extent than the conventional methods; using the water insoluble, thiol containing task specific ionic liquid.

           

Key words: Task- specific ionic liquid (TSIL), heavy metals, chromium, sequesterization, tricaprylmethyl ammonium thiosalicylate, tannery wastes.
