摘要
使用活性碳吸附造纸厂空气中的有机污染物,以二硫化碳解吸,使用气相色谱-质谱联用法(GC-MS)分析研究了某造纸厂4个采样点的空气质量情况。结果表明,在废纸分拣处检测到4种烷烃类的有机污染物,在造纸车间、真空泵出水口、工厂办公区都检测到芳香族有机物,其中苯和甲苯的检出率为100%;工厂办公区的污染物种类明显少于造纸车间和真空泵出水口。
In this paper, VOCs in four air samples from a paper mill were adsorbed by active carbon, and then followed by being uhrasonicat- ed in carbon bisulfide, the resulting solutions were analyzed by gas chromatography-mass spectrometry （GC-MS） analytical method. The ana- lytical results showed that four kinds of alkanes organic pollutant were detected in the waste paper sorting area, aromatic organic materials were detected in paper making plant, the outlet of vacuum-pump as well as the office area of the paper mill, where the detectable rates of benzene and toluene were 100%. The species of pollutant in the office area of the paper mill was evidently less than that of paper making plant and the outlet of vacuum-pump.
