摘　　要：介绍了环境中SO2监测的主要方法,比较了常用的溶液吸收法和被动采样法等。溶液吸收法用来测量1 h或者更短时间内环境中SO2的浓度水平,被动采样法更多地用来监测1周到1个月内环境中SO2的沉积率,在线监测技术的发展为烟气的测量和烟道的防腐蚀提供了更多的技术支撑。最后提出了今后SO2监测方法的发展趋势。The main methods for monitoring of environmental SO2 were introduced, and the commonly used solution absorption method and passive sampling method were compared. The solution absorption method is used to analyze the SO2 concentrations in the environment within an hour or even shorter time, while the passive sampling method is more frequently used to monitor the rate of deposition within one week or one month. The development of on-line monitor technology provides more technical support for the measurement of exhaust gas and anti-corrosion of flue. In the end, this article put forward the development trend of SO2 monitoring methods.
