Kinetics of thermal decomposition of ZnSO4·7H2O

The thermal decomposition of ZnSO4·7H2O was studied under non-isothermal conditions in air. The kinetics of particular stages of ZnSO4·7H2O decomposition were evaluated from the dynamic weight losses data by means of integral method. The values of the activation energy E, and the preexponential factor A of each stage of the thermal decomposition were calculated.
