Abstract:
On the basis of the Coats-Redfern's integral equation and Ozawa's equation. the probable mechanism of the dehydration process of FeC2O4 2H2O was investigated using double extrapolation. The dehydration Process includes two steps. The first step is the nuclear producing and growing process(n=1.5), G(α)= [ln(1-α)]1/1.5; the second step is a two-dimensional diffusion process, G(α)=(1-α)ln(1-α)+a: the corresponding kinetic parameters were determined.
Key words: Donble extrapolation, TG-DTA techmique, Dehydration rocess of FeC2O4 2H2O, Mechanism function
