a Photograph of the 3-electrode experimental setup used to calibrate Fe release from SS304. b Example of current and voltage data for constant current profiles at 0.5 mA, with constant pulse time but varying pulse frequencies. c Fe dose delivered in ppb quantified using ICP-OES (n = 3) corresponding to the different electrochemical profiles shown in (b). The dotted line in (c) indicates the starting concentration of Fe in the electrolyte.
