Cyclic voltammograms of 11Fe (left, 2 mM) and 11Ga (right, 2 mM). Conditions: platinum working electrode; platinum wire auxiliary electrode; saturated calomel electrode (SCE) reference electrode; 0.1 M KCl as the background electrolyte in 0.05 M phosphate buffer pH 7.0 at ambient temperature; scan rate = 100 mV s−1.
