| 中文摘要 |
| 直接进水样气相色谱法测定水和工业废水中微量含氮有机污染物具有快速、简便、精确的特点。本法用530μm熔融石英毛细管柱分离,高灵敏度的氮磷检测器,进样1μl时检测限分别为0.4μg/L、0.45μg/L、4μg/L、10μg/L.这一灵敏度可满足排污监测及环境评价的要求。 |
| 英文摘要 |
| Direct aqueous injection (DAI) gas chromatography is a rapid, simple and accurate method for the determination of nitrogenous organic pollutant at μg/L levels in water and discharsed industrisl water. In this method a 0.53 mm id. fused silica capillary column was used in order to enhance resolution. Bacause of the high sensitivity of nitrogen phosphorous detector a 1μl sample injection is enough fot the determination with satisfactory accuracy, precision and sensitivity. |
