where I is the current density, t is the operation time (s), Mw is
molecular weight of the substance, F is Faraday’s constant
(96485 C/mol), z is the number of electrons involved in the reaction
(3 for Al3+) and m is the mass of the aluminum dissolved.
When the initial pH was 3, aluminum concentrations dissolved
from Cells A + C and Cell C were close to theoretical values
