Abstract
The effects of gamma radiations on the kinetic parameters of the dynam ic thermal decomposition-gasification reactions of ammonium oxalate mo nohydrate have been investigated using differential thermal analysis a nd thermogravimetry techniques. Kinetic analysis of the dynamic TG res ults are discussed in view of a composite integral method in compariso n with the integral methods due to Coats and Redfern and to Ozawa. The activation parameters for the non-irradiated and irradiated samples a re calculated and the results of the different methods of data analysi s are compared and discussed.
