摘要：
Using a gasometric method the petsulfate decomposition rate in aqueous solutions at different pH values in the temperature range 323 K < T < 363 K has been studied. In all cases oxygen evolution is quantitative and proceeds by radical mechanism. The activation energy of oxygen evolution is practically equal to the value obtained by using different methods. A new mechanism is proposed based on a "solvation effect".
