Abstract
Kinetic analyses were performed on potassium sodium tartrate tetrahydrate (KNaC4H4O6 center dot 4H(2)O) using TG/DTA measurement in N-2. The thermal behaviour and the effect of heating rate on the kinetics were investigated. To estimate the activation energy E of decomposition, the Ozawa and Kissinger iso-conversional method were applied. All stage's of dehydration are governed by nucleation model F1 [g(alpha) = (1-alpha)(-1)].
