摘　　要：介绍并分析了近年来国内外锅炉排放的烟气尾气中汞的监测方法,经过对技术国情贴合性、操作难度以及经济因素的考虑,建议结合安大略法和原子荧光法,将吸收瓶组进行改进,装入冷原子分光光度法吸收液,接于直接测汞仪或连接手机的SWASV-伏安检测系统前,进行等速采样,既可满足愈发严苛的环境监测要求,又可控制国内锅炉烟气尾气中汞的排放。The methods of monitoring mercury in boiler exhaust gas at home and abroad in recent years will be introduced and analyzed.After consideration of technology-national conditions fit,operational difficulty and economic factors.It will be recommended to combine Ontario method and AFS,improve the bottle group,put in the absorption liquid of CAAS,connect it to the direct mercury measuring instrument or the SWASV-voltammetry detection system connected to the mobile phone,and perform isokinetic sampling.It will not only meet the strict environmental monitoring requirements,but also control the emission of mercury in the exhaust gas of domestic boilers.
