“…It displays the two characteristic vibration bands found in all GR compounds at about 430 and 500 cm −1 [7][8][9]. The small band at 1,346 cm −1 corresponds to the symmetric stretching mode of the COO group of the formate ion.…”

A new methodology was envisioned in order to prepare green rust compounds build on organic anions that could intervene in microbiologically influenced corrosion processes of iron and steel. The formate ion was chosen as an example. The formation of rust was simulated by the oxidation of aqueous suspensions of Fe(OH) 2 precipitated from Fe(II) lactate and sodium hydroxide, in the presence of sodium formate to promote the formation of the corresponding green rust. The evolution of the precipitate with time was followed by transmission Mössbauer spectroscopy at 15 K. It was observed that the initial hydroxide was transformed into a new GR compound. Its spectrum is composed of three quadrupole doublets, D 1 (δ=1.28 mm s −1 , Δ=2.75 mm s −1 ) and D 2 (δ=1.28 mm s −1 , Δ= 2.48 mm s −1 ) that correspond to Fe(II) and D 3 (δ=0.49 mm s −1 , Δ=0.37 mm s −1 ) that corresponds to Fe(III). The relative area of D 3 , close to the proportion of Fe(III) in the GR, was found at 28.5±1.5% (∼2/7). Raman spectroscopy confirmed that the intermediate compound was a Fe(II-III) hydroxy-formate, GR(HCOO − ).

“…The occurrence of multiple bands in the 3100-3400 cm −1 (respectively 2300-2700 cm −1 ) region was attributed to structurally distinct H 2 O (respectively D 2 O). In their work, Bonin et al [21] and Simard et al [22] studied the formation of a carbonate green rust in carbonated water. Especially, the assignment of the Fe 2+ -OH and the Fe 3+ -OH vibration bands in the Raman spectra was made using a deuterated solvent.…”

International audienceIn several contexts such as cultural heritage, oil and gas or nuclear waste disposal, the long-term corrosion mechanisms of iron in anoxic soils are studied. For this purpose, corrosion layers formed on ferrous archaeological artefacts from the site of Glinet (16th century, Normandy, France) were characterised. The main phases identified are siderite (FeCO3), chukanovite (iron hydroxycarbonate: Fe2(OH)2CO3 and magnetite (Fe3O4). In order to provide reliable Raman references for further studies on carbonated systems, the iron hydroxycarbonate (chukanovite) was synthesised on iron discs. The corrosion mechanisms were investigated by re-corroding the archaeological samples in a deuterated solution. Raman characterisation on cross sections inside the layer revealed the presence of deuterated chukanovite, allowing the deuterium tracing of the spreading of the corrosion. A set of chukanovite samples was synthesised with various D/H ratios. Using these reference data, the proportion of deuterated chukanovite in re-corroded artefacts was evaluated, and the corrosion rate was estimated as less than 1.6 µm/year
