摘要：Liquid-liquid extraction of metals using new synthetic N,N-bis(1H-pyrazolyl-1-yl) derivatives as newextractants was studied. The extractability for Fe2+, Zn2+, Cu2+, Co2+, Cd2+ and Pb2+ from the aqueous phase wasdetermined by atomic absorption. The competitive extraction and the effect of pH were also investigated. Wefound high selectivity towards Fe2+ (68.03!%),Cu2+ (44.15%), Pb2+ (32.12%) and Cd2+ (26.22%) respectively. Inaddition, the geometry and the electronic structure were carried out by DFT calculations.
