| 摘 要： | 采用不锈钢采样罐采集全量空气样品,使用空气预浓缩冷冻的方法从空气样品中提取二硫化碳,经气相色谱/质谱仪测定,判断确定空气恶臭物质的种类和污染来源。方法的最低检测浓度为0.003mg/m3,能够满足中国(TJ36-79)居住区大气中有害物质二硫化碳的最高容许浓度0.04mg/m3(一次值)标准的测定要求。

| Abstract: | To trace source and identify substances of an offensive odor emitted in Nanjing city sometimes,carbon disulfide was determined by sampling ambient air with specially prepared canisters,and was analyzed by gas chromatography-mass spectrometer after extraction with pre-concentrator.The lowest concentration of the method was 0.003 mg/m~3,and it satisfied the detection(requirement) for 0.04 mg/m~3 which is the permitted concentration of carbon disulfide for ambient air standard of hazard substances in inhabitant area of China(TJ36-79). |
