Abstract: The thermal behavior of ferrous oxalate dihydrate (FeC2O4·2H2O) was studied by thermogravimetry and differential thermal analysis (TGA and DTA). Three steps could be deduced for the decomposition from the TG,DTG and DTA curves obtained. One of the steps was the dehydration, the mass loss was 20.1%(the found value was in good agreement with the calculated value). Mathematical analysis with the integral and differential methods showed that the kinetics of dehydration of FeC2O4·2H2O could be explained by F1 mechanism in nitrogen atmosphere. The kinetic equation of dehydration of FeC2O4·2H2O could be expressed as: dα/dt=6.25×1019[exp(-170.27×103/RT)](1-α)
