为测定某化工废水排污沟底泥中多种有机污染物,建立了气相色谱(GC)分析方法。GC测定用电子俘获检测器(ECD)及火焰电离检测器(FID)两种检测器。每种检测器测定时均用两个极性不同的色谱柱分离、定性,结果较为可靠。比较了底泥样品三种不同提取方法的效果。所提供方法操作
In order to determine a variety of organic pollutants in sediment of a chemical wastewater discharge ditch, a gas chromatographic (GC) analytical method was established. GC determination with electronic capture detector (ECD) and flame ionization detector (FID) two detectors. Each detector was measured with two different polarity of the column separation, qualitative, the result is more reliable. The effects of three different extraction methods on sediment samples were compared. Provided by the method of operation
