Influence of chlorinated solvents on polarization and corrosion behaviour of iron in borate buffer

Composition and structure of iron oxidation surface layers produced in weak acidic solutions

“…Comparison of the products observed after iron corrosion in this work to those, mainly oxides (magnetite, maghemite), reported in literature [18,20,30, and references therein] could suggest significant discrepancy. In fact, lepidocrocite undergoes transformation in the presence of Fe 2+ ions to form magnetite in the following reaction:…”

“…The results were reported for iron in contact for about 70 h with an aqueous solution in the pH range 7-10. After a shorter reaction time, the surface layer produced was too thin to be detected [18][19][20].…”

Influence of dissolved inorganic carbon and calcium on gas formation and accumulation in iron permeable reactive barriers

“…The reduction of water (Reardon, 1995) or of hydrogen ions formed by dissociation of water (Bonin et al, 1998;Gillham and Ohannesin, 1994), respectively, leads to formation of adsorbed atomic hydrogen that recombines to molecular hydrogen (H 2 ). When the maximum solubility of a gas is exceeded, exsolution leads to formation of gas bubbles with partitioning of further dissolved gases.…”

Calcite precipitation dominates the electrical signatures of zero valent iron columns under simulated field conditions

“…Magnetite is a major precipitate during anaerobic corrosion of iron via re-precipitation of dissolved iron and autoreduction of ferric iron on ZVI surfaces (Pryors and Evans, 1950;Bonin et al, 1998). Other than magnetite, calcite is a major mineral phase in systems with high calcium and bicarbonate concentrations through the following reactions (Wolery, 1992 …”
