Extraction and Binding Efficiency of Calix[8]arene Derivative Toward Selected Transition Metals
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 (Co2+, Cd2+, Ni2+, Pb2+ and Cu2+). Picrate salt solutions of these metals were used in the liquid-liquid extraction experiments. It is apparent fro...

| Summary: | 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 (Co2+, Cd2+, Ni2+, Pb2+ and Cu2+). 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 Pb2+>Cu2+>Ni2+>Co2+>Cd2+ being observed. Highest extraction efficiency has been observed for Pb2+ and Cu2+ 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. |
