The decomposition of Fe2 (C2O4)3.5H2O and K3 (Fe(C2O4)3).3H2O supported on active carbon in hydrogen has been investigated by gas chromato-graphy and Mossbauer spectroscopy. It was found that the thermal decomposition of supported species was different from the corresponding unsupported compounds. The interaction of the compounds with active carbon lowered the temperature of decomposition of the coordination compounds and facilitated the reduction of ferric oxalate to ferrous oxalate. For K3(Fe(C2O4)3)-active carbon system, the reduction could proceed at room temperature. The interaction of the metal ions with support led to a high dispersion of solid products on active carbon, thus the reduction of Fe(II) became difficult. In- spite of , the difficulty of decomposition of H2C2O4.2H2O, which sublimated above 100℃, and of K2C2O4.2H2O, which decomposed only at a very high temperature, both compounds supported on active carbon could be decomposed below 100℃ due to the interaction between the ligands and the support. Compared with the pure compounds, the larger load the amount of on support and the higher the ratio of C2O42+ to Fe (Ⅲ),the more it was like the decomposition of supported ferric oxalate, which might be the result of the dissociation adsorption in the impregnation process. Mossbauer spectroscopy revealed that the surface atoms of active carbon entered the coordination sphere of Fe(Ⅲ), altered its chemical environment and new surface compounds formed. The Mossbauer parameters of Fe2(C2O4)3-5H2O were different from K3 (Fe (C2O4)3) -3H2O, but when they were supported on active carbon, the parameters of Fe(Ⅲ) were very close, so that they resembled each other in their chemical environment and decomposition behavior.
