Abstract

Thermal decomposition of Pu(C2O4)2·6H2O, Pu2(C2O4)3·10H2O and Np(C2O4)2 ·6H2O has been studied by using combination of gas chromatography, infrared spectroscopy, spectrophotometry and complex thermal analysis. We also investigated the decomposition of Pu oxalate under its α-radiation. The reduction of Pu(IV) to Pu(III) has been confirmed. We found Np(V), which is formed from Np(IV), on the basis of infrared and absorption spectra of the intermediate compounds.
