摘　　要：生物质锅炉废气中含有高浓度一氧化碳、氮氧化物、甲烷、少量二氧化硫,以及脱硝过程中产生的氨逃逸等,非分散红外吸收法监测二氧化硫甲烷将对二氧化硫的测定引入5%左右的正干扰;高浓度一氧化碳、氨气等,对常用的其它监测方法也产生干扰。现对干扰存在的原因进行逐一分析讨论,归纳总结解决问题的办法,为环境监测工作提供参考。Biomass boiler exhaust gas contains high concentrations of carbon monoxide,nitrogen oxides,methane,a small amount of sulfur dioxide,as well as ammonia escape generated during denitrification.Non dispersed infrared absorption method for monitoring sulfur dioxide methane will introduce about 5%positive interference to the determination of sulfur dioxide.High concentrations of carbon monoxide,ammonia,etc.also interfere with other commonly used monitoring methods.This paper analyzes and discusses the causes of interference one by one,summarizes the solutions to the problems,and provides reference for environmental monitoring work.
