Abstract

The final products of the gamma radiolysis of cesium tris (oxalato) ferrate (III) dihydrate have been identified by Mössbauer spectroscopy and thermogravimetric analysis as a mixture of Cs2Fe(ox)2.4H2O and Cs2Fe(ox)2 in equivalent proportions. The tetrahydrated compound can also be made by wet synthesis whereas the anhydrous salt can be obtained from thermal decompositions of either the tetrahydrated ferrous salt at 160°C or of the ferric complex at 285°C. The radiolytic decomposition proceeds as a first-order process due to the original compound depletion and to the radiolytic stability of the radiolytic products.
