| 摘 要： | 采用固相萃取-GC／MS法测定水中6种邻苯二甲酸酯类有机污染物，比较了不同固相萃取柱对萃取效果的影响，优化了水样pH值、水样流量、穿透体积、洗脱溶剂、洗脱剂体积、洗脱流量等萃取条件。方法在0．050μg/L-800μg/L范围内线性良好，检出限为0．008μg/L～0．03μg／L，标准溶液测定的RSD≤10．5％，实际水样加标回收率为80．0％-100％。

| Abstract: | The 6 kinds of phthalate esters （PAEs） in water were determined by GC/MS with solid-phase extraction（SPE）. The efficiencies of SPE were compared for optimization of the pH of water samples, water flow rate, breakthrough volume, eluting solvent and volume, eluting rate, etc. The linearity was good from 0.050μg/L to 800 μg/L and the detection limits were from 0. 008 μg/L to 0.03 μg/L. The RSD of standard solution was ≤10.5%. The recoveries of practical samples were from 80.0% to 100%. |
