Dissolution process of the oxides in various environments has attracted much attention because of its impact in environmental science and technology. Extensive investigation of the dissolution of oxides using optical, capacitance, and electroanalytical methods have revealed that the dissolution rate of oxides depends on the type of anions, temperature and the solution pH. Polarization measurements can offer a simple and rapid technique for the study of the dissolution of oxides on Al but has been mainly employed to study pitting behavior of in chloride solutions. The present study demonstrates the applicability of polarization measurement in determining the dissolution characteristics of pure Al in various solutions that relate to the corrosion behavior of Al. The simple cyclic polarization study has shown that it is possible to rapidly characterize growth and dissolution behavior of Al in different solutions.
