Abstract
A new procedure for the synthesis of Prussian Green, using HNO3 or dioxane media, is proposed. Synthesis from aqueous H3Fe(CN)6 is described. I.R. spectra of solids and of colloidal suspensions of Prussian Brown, Prussian Green and Prussian Blue are recorded and discussed. An explanation for the 1960 cm−1 vibration stretching is proposed. The identity between Prussian and Turnbull Blue is questioned owing to I.R. results. A mechanism is proposed for the suggested oxyreduction reaction, based on analytical and mass spectroscopy data. Protonation of the complexed iron plays an important role in these reactions. Explanations for contradictory properties and Mössbauer results cited in literature are given.Keywords
