| 摘 要： | 采用吹扫捕集-气相色谱／质谱联用法测定水中9种酯类有机物，加入硫酸钠盐提高灵敏度，当硫酸钠过饱和时，吹扫捕集效率最高。9种酯类有机物在一定的质量浓度范围内线性关系良好，方法检出限为0．14μg／L～0．25μg／L，模拟样品平行测定的RSD为0．6％～1．8％，加标回收率为80％～106％。

| Abstract: | The method was established for determination of nine ester compounds in water by gas chromatog- raphy-mass spectrometry with purge and trap. The sensitivity of method was improved by increasing sodium sul- fate quantity. Purge and trap obtained the highest efficiency when sodium sulfate became supersaturate. Calibra- tion curves exhibited good linearity in certain concentration. Detection limits ranged from 0. 14 μg/L to 0.25 μg/L. RSD of simulation duplicated samples ranged from 0.6% to 1,, 8%. The spiked recoveries ranged from 80% to 106%. |
