| 中文摘要: |
| 水样经聚四氟乙烯滤头过滤，直接用超高效液相色谱-三重四极杆串联质谱（UPLC-MS/MS）同时测定甲萘威、呋喃丹和阿特拉津。通过试验考察不同材质滤头和各仪器条件对测定的影响，并确定最佳分析条件，使该方法在0.01 μg/L~10.0 μg/L范围内线性良好。甲萘威、呋喃丹和阿特拉津的方法检出限分别为6.1 ng/L、2.8 ng/L、3.1 ng/L，空白水样的3个质量浓度加标回收率在96.4%~110%之间。该方法用于测定实际水源水及饮用水中的甲萘威、呋喃丹和阿特拉津，结果均未检出，实际水样平均加标回收率为81.4%~97.2%。 |
| 英文摘要: |
| Carbaryl, carbofuran and atrazine in water were detected simultaneously by UPLC MS/MS after filtered thought 0.22 μm filter. The effect of instrument conditions and filter materials on the determination of carbaryl, carbofuran and atrazine were investigated. Under the optimized conditions, the linear range was 0.01 μg/L～10.0 μg/L.The detection limits for carbaryl, carbofuran and atrazine was 6.1 ng/L, 2.8 ng/L and 3.1 ng/L, respectively. Average recoveries at three spiking levels were in the range of 96.4%～110%. The established method was applied to detect carbaryl, carbofuran and atrazine in source water and drinking water. All of the target compounds were not detected. The average recoveries of actual sample spiked with carbaryl, carbofuran and atrazine were between 81.4% and 97.2%. |
