In the present study, neem-alginate-clay based controlled pesticide release formulations were characterized by thermogravimetric analysis and various kinetic and thermodynamic parameters for thermal degradation viz. Energy of activation (Ea), Arrhenius pre-exponential factor (A), activation entropy (ΔS*), activation enthalpy (ΔH*) and free activation energy (ΔG*) were calculated by using integral Coats-Redfern method. Thermal degradation obeys the Jander model equation i.e. D3 (Three dimensional diffusion) solid state mechanism.
