Abstract: Dehydration process of cobalt(Ⅱ) oxalate dihydrate in solid state was studied by double extrapolation method based on Coats-Redfern's integral equation and Ozawa’s equation. The dehydration of CoC2O4?2H2O was described by two steps. The probable mechanisms of each step were determined. Furthermore, the corresponding kinetic parameters were obtained.

Key words: Double extrapolation, Dehydration process of CoC2O4?2H2O in solid state, TG-DTA technique
