| 中文摘要: |
| 以活性炭吸附环境空气中1,2- 环氧丙烷, 用二硫化碳洗脱,OV- 101:30 m×0.32 mm×0.25μm 毛细管柱低温分流进样分离, 氢火焰离子化检测器测定, 保留时间定性, 峰高定量, 采样吸附率达99% 。 方法有较宽的线性范围, 较高的灵敏度和精密度。 当采样体积为30 L 时,1,2- 环氧丙烷的检测限为0.005 mg/m 3 。 |

| 1,2- Epoxypropanein ambientair wasfirstabsorbed by activecarbon,eluted by CS 2 , separated bythetypeof capillarycolumnofOV- 101:30 m×0.32 mm×0.25μm underlow temperature. Thenit was determined by hydrogen flame ionization detector,identified byretentiontime, quantified with peak height,thesampling adsorption efficiency w as 99%. This method realized widelineallimit, high sensitivity, precision. When the sample c s volume w as 30 L,the detection limit was 0.005 mg/m 3 . |
