| 中文摘要: |
| 采用气袋采样气相色谱法测定固定污染源废气中的氯乙烯和丙烯醛，通过优化试验条件，使方法在0100μmol/mol～100μmol/mol和100μmol/mol～100μmol/mol范围内线性良好，方法检出限均为003 mg/m3。氯乙烯、丙烯醛3个摩尔比水平的空白加标回收率分别为860%～108%、880%～108%，测定6次结果的RSD分别为50%～67%、40%～54%。将该方法用于测定实际样品，加标回收率为900%～103%。 |
| 英文摘要: |
| A method of bag sampling gas chromatography was established to determine vinyl chloride and acrolein from stationary source emission. The method had good linearity in ranges of 0100 μmol/mol~100 μmol/mol and 100 μmol/mol~100 μmol/mol. The limit of detection（LOD） of both were 003 mg/m3. The spiked recoveries of blank samples at 3 mass concentration levels of vinyl chloride and acrolein were 860%~108% and 880%~108% respectively， and the relative standard deviations（RSDs） of 6 measurements were 50%~67% and 40%~54% respectively. This method was used for actual sample determination， and the spiked recoveries were 900%~103%. |
