摘要：In this article we have explored the extraction efficiency as well as binding ability of calix[8]arene derivative (3) for selected transition metal ions (Co +2,Cd +2,Ni+2,Pb 2+ and Cu 2+ ). Picrate salt solutions of these metals were used in the liquid-liquid extraction experiments. It is apparent from the results that ligand 3 shows appreciable high extraction of transition metal cations,with the relative order Pb 2+>Cu 2+>Ni+2>Co +2>Cd +2 being observed. Highest extraction efficiency has been observed for Pb 2+ and Cu 2+ i.e. 95 and 91% respectively. The significant extraction and complexation ability for these metal ions may be attributed to the nature,size,structure and geometry of both ligand and metal ions..
