CFCs生产企业废水及产品成分快速检测分析

摘要

To rapidly identify and provide technical assistance for predicating whether the factory is broking laws to produce CFCs, a Headspace-GC-MS method was proposed to rapidly analyze of trichloromonofluoromethane, dichlorodifluoromethane and carbon tetrachloride in the products and effluent discharged by the companies employing the vehicular GC-MSD technology. The headspace-GC-ECD method was used to analyze the concentration of carbon tetrachloride in waste water, to make sure if the monitoring data coincide with the emission standard.%采用车载GC-MS技术，建立了顶空-GC-MS方法对CFCs产品组分及排污废水中三氯一氟甲烷、二氯二氟甲烷、四氯化碳等成分进行监测分析，实现了快速鉴定企业是否违规生产CFCs相关产品，对于判定企业是否违规提供技术依据。同时，采用顶空-GC/ECD方法对废水中的四氯化碳进行定量分析，以排查企业是否超标排污。
