Sodium hydrogen peroxide sodium chloride adduct was prepared with low concentration (30 wt%) of hydrogen peroxide, the content of each component was close to the theoretical value, the purity was 99 3%; at 32 3K and 333K , The kinetics of 4Na2 SO4 · 2H2 O2 · NaCl decomposition in alkaline aqueous solution was studied. The results show that under different conditions, the decomposition is a first-order reaction; with the increase of temperature and pH, the decomposition rate is accelerated. When the confidence level is 95%, the joint confidence domains of k and C0 are elliptical and the area is small, and the parameters obtained are of high precision. The optimized model can accurately describe the effect of 4Na2 SO4 · 2H2 O2 · NaCl on alkaline Decomposition process in aqueous solution.
