where I corresponds to current intensity (A), tEC to the time of ECG
process, M to the molar ratio of the metal (g/mol), z to the valence
electrons of the metal and F to the Faraday’s constant
(96485 C/mol). The experimental dissolution value was determined
by the difference between the initial and final mass of the zinc electrode,
i.e. before and after the treatment process. In theory, the zinc
mass loss would be 3.07 g. The values experimentally obtained support
the theoretical with the exception of the last reuse, in which
the anode would not have much material to dissolve into solution.
