水中臭氧浓度的检测方法

The Methods of Measuring Ozone Concentration in Water

目前检测水中臭氧浓度的方法很多,为使检测方法的选择有章可循,详细论述了应用碘量法、比色法、紫外分光光度法、电位法和电量法检测水中臭氧浓度的原理和方法。从检测精度、连续性、水质要求和技术经济等方面考虑,分析了各种检测方法的特点及其适用场合,指出在具体应用时应根据检测方法的特点、对检测精度的要求和检测现场的实际情况,选择适当的检测方法。

At present, there are many methods to measure ozone concentration in water. To make a way to select a suitable method, the principles of iodimetry, colorimetry, spectro photometry, potentiometer and coulometer are discussed in detail. According to measuring precision, continuity, concentration of ozone and economy, the characteristics and befitting situation of the different methods are analyzed. When applied, the method should be selected on the bases of the characteristics of method, requirements of precision, actual situation of spot and so on.
