Abstract

The thermal decompositions of K3Fe(ox)3 3 H2O and K2Fe(ox)2 2 H2O in nitrogen have been studied using Mössbauer spectroscopy, X-ray diffraction and thermal analysis methods in order to determine the nature of the solid residues obtained after each stage of decomposition. Particularly, after dehydration at 113°C, the ferric complex is reduced into a ferrous compound, with a quadrupole splitting of 3.89 mm/s, which corresponds to the anhydrous form of K2Fe(ox)2 2 H2O.
