摘    要:目的 研究臭氧气体和臭氧水溶液中各种臭氧浓度测定方法的特点,同时研究了温度对臭氧在水中溶解度的影响。方法 用中性碘化钾碘量法和硼酸碘化钾比色法测定臭氧水中的臭氧浓度,用碘量法(中性碘化钾法、硼酸碘化钾法、碱性碘化钾法)和紫外光度法测定臭氧气中臭氧浓度。结果 在对同一臭氧水的臭氧浓度进行测定时,中性碘化钾碘量法测定结果高于硼酸碘化钾比色法测定结果。与标准方法紫外光度法相比较,中性碘化钾法、硼酸碘化钾法、碱性碘化钾法测定同一臭氧气体的测定结果相对误差分别为 18%、 4%、 9.3%。结论 硼酸碘化钾法较为准确,可用作为中高浓度的臭氧气体和臭氧水理化检验的标准方法。

Abstract:In this paper, characteristic of different methods for the determination of ozone in water and in gas were studied and the influence of temperature on solubility of ozone in water were also studied. When neutral iodometric method and method of boric acid potassium iodide photometry applied to a sample of ozone in water, the results of the former method was greater. When neutral, alk and boric acid iodometric method applied to a sample of ozone in a gas, the results of them were respectively 118% , 109.3% and 104% of (he result of UV photometry which is took for a standard method by many countries and organizations, therefore boric acid iodometric method can be considered as a standard method for the determination of ozone in water and in gas.
Keywords:Ozone  Disinfactant  Standard Method
