| 中文摘要 |
| 用Tenax作为吸附剂捕集大气中的痕量溴甲烷,用气相色谱法和光离子检测器,对其进行检测,相对偏差为0.0521,最小检测限为10pg.室内外大气中的浓度分别为24×10-12(V/V)和77.4×10-12(V/V),污染在10-11(V/V)水平。 |
| 英文摘要 |
| Atmospheric CH3Br was trapped by Tenax adsorbent and was determined by gas chromatography with photoionization detector. The CH3Br concentrations in indoor and outdoor are 24×10-12 (V/V) and 77.4×10-12 (V/V).The standard deviation and detection limit for the method are 0.0521, 10 pg respectively. The level of CH3Br pollutions is 10-11(V/V). |
