| 摘 要： | 该文研究了臭氧在气态和水溶液中的分解规律,主要研究了温度和pH值的影响,并获得了不同温度、pH值下臭氧分解的半衰期.实验结果表明:臭氧在气态条件下和在水溶液中,其分解速度随温度升高而加快;pH值小于2时,臭氧在水溶液中的分解速度随pH值的升高而减慢;pH值介于3~6之间时,分解速度随pH值升高而加快;pH值大于6时,分解速度极快.

| Abstract: | Ozone decomposition rules in gaseity and aqueous solution, mainly the influence of temperature and pH value, are discussed in this paper. Half lives of ozone decomposition under different temperatures and pH values are obtained. The following conclusions are drawn from experimental results. In a gaseity or aqueous solution the ozone decomposition rates are accelerated with rise of temperature. When pH value is less than 2, the ozone decomposition rates decrease with the rise of pH value. When pH value is between 3 and 6, the ozone decomposition rate increase with the rise of pH value. When pH value is more than 6, the ozone decomposition rate becomes very high. |
