摘要
采用燃烧氧化-非分散红外吸收法,建立了固定污染源中总有机碳的测定方法。采集并分析了上海市汽车制造业喷涂车间总有机碳(TOC)的浓度,并与现行排放标准进行了比较。结果表明,标准曲线的线性较好,精密度较高,方法检出限为9.0 mg/m^3;所测气样中TOC浓度在色漆工艺为75.1 mg/m^3,中漆工艺为86.1 mg/m^3,清漆工艺为224.5 mg/m^3,中涂烘房为92.1 mg/m^3。将同批次样品的TOC浓度与VOC浓度进行比较,发现在不同车间工艺中,TOC浓度最高,VOC浓度次之,TOC浓度一定程度上可以反映VOC的浓度。
The total organicmanufacturing industry in Shanghaicarbon （TOC） pollution situation from stationary source emission in automobilewas evaluated based on the combustion oxidation-nondispersive infrared absorptionmethod. Results showed that the mass concentration of total organic carbon （TOC） under four different painting workshopswere 75.1, 86. 1, 224.5 and 92. 1 mg/m3, respectively. Compared with the current emission standards in China,concentration of total organic carbon （TOC） was higher than volatile organic compounds （VOCs） concentration on thesame samples, which showed that total organic carbon （TOC） could reflect total organic carbon （TOC） situation.
