研究了pH值对臭氧在水中分解动力学的影响。在pH 1-8范围内，动力学符合二级反应方程。从大约pH 3开始，在19 A ℃下常数对数的pH依赖性对应于方程logk= -2.66 +（0.49 +/- 0.03）pH。发现臭氧分解的活化能为76.0 +/- 8.3 kJ/mol。
The influence of pH on the kinetics of ozone decomposition in water was studied. Over the pH range 1-8, the kinetics was well described by a second-order reaction equation. Starting with approximately pH 3, the pH dependence of the logarithm of the constant at 19A degrees C corresponded to the equation logk= -2.66 + (0.49 +/- 0.03)pH. The activation energy of ozone decomposition was found to be 76.0 +/- 8.3 kJ/mol.
