香烟烟雾中有机污染物的测定

Determination of Organic Pollutants in Cigarette Smoke

将香烟烟雾中有机污染物低温下富集在玻璃纤维滤膜上,用溶剂萃取并洗涤萃取液,经柱色谱分离成脂肪烃、多环芳烃、极性化合物三种馏分,再用色谱-质谱联用法测定了香烟烟雾冷凝液中56种有机污染物。

The organic pollutants in cigarette smoke are collected on a glass fiber membrane and extracted by solvents at low temperature, the extract is washed and separated into three fractions e.g. fatty hydrocarbon, polynuclear aromatic hydrocarbon and polar compounds, by column chromatography, 56 kinds of organic pollutants in cigarette smoke condensate are determined by using GC-MS.
