【摘要】 采用GC/MS法分离测定油漆行业废气污染物化学成分,利用化学计量学解析法(CRM)对重叠的色谱峰进行解析,得到各成分的纯色谱曲线和质谱,通过质谱库对解析的纯组分进行定性,用解析色谱曲线积分法进行定量。从25个色谱峰中解析出了49个组分,按检索相似度大于90%的原则,鉴定出了其中40个化合物,占总含量的92.3%。废气污染物的主要成分为苯系物和烷烃,分别占总含量的46.8%和27.2%。更多还原

【Abstract】 A new method of analyzing the chemical constituents in waste gas pollutant of paint was industry were introduced.Analysis of chemical constituents in waste gas pollutant of paint industry was performed with two dimensional gas chromatography-mass spectrometry(GC/MS) coupled with chemometrics resolution method(CRM).By means of these methods two-dimensional data,49 chemical components in waste gas pollutant of paint industry were obtained from 25 chromatographic peaks and 40 compounds were determined qualitatively and quantitatively,amounting to 92.3% total contents of waste gas pollutant of paint industry.The main components in waste gas pollutant of paint industry were benzene series and alkane,amounting to 46.8% and 27.2%,respectively.更多还原
