The effect of the low-oxidation-state metal ion reagent tris-picolinatovanadium(II) formate on the surface morphology and composition of crystalline iron oxides

Abstract

The LOMI (low-oxidation-state metal ion) process is used widely in the decontamination of water reactor systems. An attempt has been made to elucidate the mechanism of dissolution by reference to a number of single crystals of iron oxides polished on specific crystallographic planes, e.g. magnetite, Franklinite and haematite. These have been studied by a combination of electron-spectroscopic techniques such as X-ray photoelectron spectroscopy, Auger electron spectroscopy and Mössbauer spectroscopy. Electron microscopy and chemical kinetic measurements have also been undertaken.
