摘要：
Anodic dissolution of Al in concentrated solutions of NaOH has been studied by potentiostatic and potentiodynamic method. The obtained polarization curves pointed out that, in strong alkaline solutions different from the cases of the neutral aqueous solution and acidic solutions. In strong alkaline solutions no passive - active transition up to high overvoltages was observed. The increase of NaOH concentration led to in all the cases to the increase of the dissolution rate of aluminium in according to the dissolution proposed mechanism and Pourbaix diagram.
