摘要: In this paper new extractants, that have the potential to be sustainably regenerated, are proposed for metal removal from aqueous phases. These extractants a novel class of ionic liquids (ILs) with unsaturated fatty acids as anions (oleate and linoleate). The advantages using these ILs their simple synthesis, sustainability (fatty renewable), biocompatibility non-toxicity. This makes “simpler greener” compared other solvents used extraction. newly synthesized were evaluated extraction Li, Na, K, Mn(II), Fe(II), Zn(II) chlorides solutions. No or negligible efficiencies observed alkali salts, but excellent (>99%) obtained period IV transition salts.
