摘要
针对定电位电解法(HJ/T57—2017)、非分散红外吸收法(HJ629—2011)与便携式紫外吸收法(HJ 1131—2020)三种方法在测定固定污染源废气中的二氧化硫项目过程中所存在的一氧化碳、甲烷等气体的干扰问题,依据现场监测与实验室分析,通过比较日常污染源监测中三种监测方法在污染源监测中存在的数据差异,分析干扰气体对二氧化硫测定结果的影响,探讨监测过程中消除干扰影响的方法,并对检测过程应注意的环节作简要说明与方法探讨。
In response to the interference issues of carbon monoxide,methane,and other gases in the determination of sulfur dioxide in fixed pollution source waste gas using three methods:constant potential electrolysis method(HJ/T57—2017),non dispersed infrared absorption method(HJ629—2011),and portable ultraviolet absorption method(HJ 1131—2020),based on on-site monitoring and laboratory analysis,by comparing the data differences of three monitoring methods in daily pollution source monitoring,this paper analyzes the impact of interfering gases on the measurement results of sulfur dioxide,explores methods to eliminate interference effects in the monitoring process,and briefly explains and explores the steps that should be paid attention to in the detection process.
