A COMPUTER-PROGRAM FOR KINETIC-ANALYSIS OF NONISOTHERMAL THERMOGRAVIMETRIC DATA

A computer program in BASIC which enables regression analysis and determination of kinetic and thermodynamic parameters from experimental TG/DTG non-isothermal thermogravimetric data is presented. This program allows the Freeman-Carroll, Horowitz-Metzger, Coats-Redfern and Doyle (modified by Zsako treatments) methods to be performed for up to 14 different solid-state rate-controlling reactions, including nth-order, Avrami-Erofeev, phase boundary movement and diffusional models. Data from the literature and the dehydration of calcium oxalate monohydrate were tested as examples of the application of this program.
