气质联用快速检测皂化废水中的特征有机污染物

Rapid determinationof the particular pollutant in the saponification wastewater by gas chromatography mass-spectrometry

采用气相色谱-质谱联用快速检测皂化废水以及各处理工序段出水中的有机物,筛选出影响处理效率的特征有机污染物二氯异丙醚,并建立了二氯异丙醚的线性方程,相关系数R=0.9995。通过对各处理工序段出水中二氯异丙醚的定量分析,发现整个处理工序对二氯异丙醚的降解存在一定的阈值。

Gas chromatography-mass spectrometry（GC-MS） was used for rapid detection of organic pollutant in saponification wastewater and the effluent of each treatment process.A characteristic organic pollutant called dichloroisopropyl ether influencing the treatment efficiency was selected and the linear equation of dichloroisopropyl ether was established.The correlation coefficient was 0.9995.Based on the quantitative analysis of dichloroisopropyl ether in the effluent of each treatment process,it was found that there was a certain threshold for the degradation of dichloroisopropyl ether in the whole treatment process.
