固定源废气中汞的检测方法探讨

Discussion on Detection Methods of Mercury in Waste Gas of Stationary Sources

针对目前我国固定源废气中汞的检测工作现状,以及国内外相关的汞检测标准,介绍了包括美国标准方法EPA Method 30B、Ontario Hydro Method(安大略法)和我国滤筒采样法、冲击瓶采样法等四种采样方法以及冷原子吸收分光光度法和原子荧光分光光度法两种分析方法,对比了各种方法的原理、适用范围及优缺点,以期为我国固定源废气汞检测提供参考。

Based on the present detection work status for mercury from the ifxed pol utional source in lfue gas iof China, as wel as the domestic and foreign relevant mercury testing standards, this paper presents the standard methods of sampling, including EPA Method 30B, Ontario Hydro Method and OHM of America, iflter canister sampling method, and shock bottle sampling method of China, and two analyzing methods include CVAAS and AFS. The paper compares the principle, application scope and advantages and disadvantages of various methods.
