| 中文摘要: |
| 采用超高压液相色谱/质谱联用法测定地表水特定项目中包括微囊藻毒素-LR在内的13种污染物，对测定条件进行优化，使得各目标化合物均能在3 min内检测完毕。试验表明，方法在各测定范围内线性良好，相关系数均>0.99，各目标化合物的方法检出限为0.12μg/L~8.40μg/L，地表水样的加标回收率在62.0%～104%之间，6次平行测定的RSD<6%。用该方法测实际水样，阿特拉津和马拉硫磷被检出，质量浓度分别为0.6μg/L和0.7μg/L。 |

| 13 pollutants in surface water including Microcystin LR were determined using ultra high pressure liquid chromatography tandem mass spectrometry method (UPLC MS/MS). The determination condition was optimized so that all the target compounds could be detected within 3 minutes. The results indicated that: all of the calibration curves showed good linear relationship with a correlation coefficient above 0.99. The determination limits of the targets were from 0.12μg/L to 8.40μg/L and the recovery rates of practical surface water samples were between 62.0% and 104%. 6 parallel samples were determined,and the relative standard deviations (RSDs) were between 1.8% and 5.7%. When determining the practical water samples using this method,only atrazine and malathion were detected,with a mass concentration of 0.6μg/L and 0.7μg/L,respectively. |
