Effective Extraction of Heavy Metals from their Effluents Using Some Potential Ionic Liquids as Green Chemicals

Abstract

Synthesis of nine Task Specific Ionic liquids (TSILs), their characterization using 1H NMR spectral studies and other physical properties and potential applications in the removal of certain heavy metals such as Nickel, Iron, Zinc, Copper and Lead has been studied. The removal of these heavy metals from the industrial effluents / contaminated water bodies using these ionic liquids has been proved to be more successful than conventional methods such as precipitation, cementation, reverse osmosis, ion exchange and adsorption.
