Na2SO4·0.5H2O2· Thermal decomposition kinetics of H2O in nitrogen, determination of Na2SO4·0.5H2O2· TG-DTG and TG-DSC curves for H2O decomposition. At 8.0 K·min-1, 6.1 K·min-1, 4.1 K·min-1 and 2.0 K·min-14 heating rates, Na2SO4·0.5H2O2· The thermal decomposition of H2O is a simple one-step reaction with a thermal decomposition temperature of 339.5 K. Multiple nonlinear regression was used to control Na2SO4·0.5H2O2· The thermal decomposition kinetic model of H2O in nitrogen was screened, and the main curve method was used to identify the decomposition model. Na2SO4·0.5H2O2· The thermal decomposition process of H2O is controlled by the three-dimensional phase interface, and the decomposition mechanism is R3 mechanism.Na2SO4·0.5H2O2· The thermal decomposition activation energy of H2O was 70.83 KJ·mol-1, which refers to the pre-factor 1.96×103.
