Abstract:

The transfer of bis-1:11 molybdosilicate heteropolyanion with dysprosium across the water/nitrobenzene interface has been investigated by chronopotentiometry with linear current scanning and cyclic voltammetry. The standard transfer potential and Gibbs energy estimated from cyclic voltammetry were 0.102V and -39.5kJ.mol-1, respectively. The kinetic parameters of the transfer were determinated by chronopotentiometry with linear current scanning.

Key words: Bis-1:11 molybdosilicate heteropolyanion with dysprosium, Water/nitrobenzene interface, Chronopotertiometry with linear current scanning, Cyclic voltammetry
