Alkaline pHs increase the dissolution rate by orders of magnitude.
Within the experimental conditions used, the supporting media does not seem to influence greatly the chemical dissolution process.
The electrochemical dissolution process depends mainly on the specific electrical charge passed. Salinity does not significantly affect the electrodissolution rate.
Good fittings between experimental and modeled data are obtained by modeling the system
with a simple model based on two assumptions: a highly segregated flow pattern and the
calculation of aluminium species and pH from a pseudoequilibrium approach.
