    Anodic Dissolution of Iron in the Solutions Simulating the Composition of Corrosive Exometabolites of Organotrophic Bacteria

    Abstract—Two Tafel regions with slopes of 0.06 and 0.09 V were observed on the dependences of the anodic dissolution of Fe in NaCl solutions with additions of NH4OH and H2O2 at low current densities. It was shown...
