Many carrier molecules were synthesised in our laboratories and successfully used for the complexation and the transport of copper(II), cadmium(II), lead(II) and mercury(II) ions. In order to minimize the amounts of organic solvents, researches have been directed towards alternative extraction systems, still based on the chelating properties of our carrier molecules but using ionic liquids as membrane. We present here results on the chelating features of simple lipophilic polyamines towards Cu(II) ions; the chelating agents were used in water/ionic liquids biphasic systems to achieve liquid/liquid extraction processes based on imidazolium-type ionic liquids.

Abstract
Many carrier molecules were synthesised in our laboratories and successfully used for the complexation and the transport of copper(II), cadmium(II), lead(II) and mercury(II) ions. In order to minimize the amounts of organic solvents, researches have been directed towards alternative extraction systems, still based on the chelating properties of our carrier molecules but using ionic liquids as membrane. We present here results on the chelating features of simple lipophilic polyamines towards Cu(II) ions; the chelating agents were used in water/ionic liquids biphasic systems to achieve liquid/liquid extraction processes based on imidazolium-type ionic liquids.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
