Abstract

Differential thermal analysis - thermogravimetry (DTA-TG) techniques were used to study the thermal decomposition reaction of Copper tartarate trihydrate. The kinetics of the non-isothermal decomposition in air were studied using thermogravimetric techniques. Analysis of the kinetic data were performed using integral methods due to composite, Coats-Redfern and Ozawa methods. The results of the kinetic analysis of the non-isothermal data were discussed in view of various solid state reaction models. The results showed that the phase boundary (R2) model gives the best fit of data. The activation parameters were calculated and discussed for each decomposition step.
