Extraction Model of Cd~(2+) and Al~(3+) Across the Water1,2-dichloroethane Interface

摘要

In the present work, the assisted transfer of Cd~(2+) and Al~(3+) by hydrophobic ligands (dibenzo-18-crown-6 and dicyclohexane-18-crown-6) across the water|1,2-dichloroethane interface have been investigated. This process was carried out using cyclic voltammetry technique. The results showed that the Cd~(2+) and Al~(3+) can be extracted across the water|1,2-dichloroethane interface by these ionophores. When the ionophores are used synergistically (in mixtures) the cyclic voltammogram showed a higher current peak, indicating that the extraction of the metals ions may be more efficient than using a single ligand.
