Calculation of parameters from glow curves for the mixed-order kinetics
Apstrakt
A new method for the calculation of parameters is proposed. The method is based on determination of the glow curve maximum and effective values of the half-width and part of the half-width on the higher temperature side. A relation between the symmetry factor as a function of the corresponding constant alpha = n(0)(h + n(0)) and the correction factor Delta is obtained. An approximate symmetry factor function is derived, which enables analytical calculation of the parameters: activation energy E, constant alpha, and pre-exponential factor s ((h)). An iterative procedure is developed for more precise calculation of these parameters. The new method is checked for some characteristic values of the parameters. The connection between the models of general and mixed-order kinetics has been described theoretically.
