| 中文摘要 |
| 文章提出了一个快速RPHPLC同时测定水体中NO3-和NO2-的新方法。使用UV210检测,磷酸为流动相,最低检出量(S/N=2):NO3-为0.08ng,NO2-为0.6ng。文章对流动相的pH及浓度进行了优化并对某地自来水及城市排放水进行了测定。全部分析时间仅为3min。 |
| 英文摘要 |
| A new and rapid method is described for the determination of NO3- and NO2- in water by RPHPLC in this paper. With the detection in UV 210nm and phosphate acid as the eluant, the minimum detection limit (S/N = 2) is 0.08ng for NO3- and 0.6ng for NO2-. How to optimize pH and concentration of the eluant on separation has been discussed as well. Moreover, samples of tap water and wastewater in a city were determined within 3 min for each by using RPHPLC. |
