Abstract

The synthesis of cobalt oxalate (II) by use strong based anion resin AV-17-8 in С₂О₄– form has been investigated. Cobalt oxalate (II) was obtained in a yield (56 %) with sulfate solution as compared with nitrate solutions (35 %). Synthesis products were investigated by chemical analysis, TGA, X-Ray diffraction and IR-spectroscopy. The chemical composition of synthesized products is СоС₂О₄^.Н₂О. It is founded that all products correspond orthorhombic modification of cobalt oxalate (II) impurity ions-free.
