|
摘要
建立吹扫捕集/气相色谱-质谱法测定水中12种酯类化合物的方法。样品经吹扫捕集、气相色谱分离、由质谱进行定量。实验结果表明在2.904～311.4μg/L范围内,方法的线性关系良好,相关系数为:0.998～0.999;加标回收率为:63.1%～142%;相对偏差为6.0%～13.8%。该方法简便、灵敏度高、可满足水中12种酯类的痕量检测要求。
A method for the determination of 12 esters in water by purge and trap/gas chromatography-mass spectrometry was established. The sample was subjected to purging and trapping, gas chromatography, and quantified by mass spectrometry. The experimental results show that the linear relationship of the method is good in the range of 2.904～311.4μg/L, the correlation coefficient is: 0.998～0.999; the recoveries of standard addition are: 63.1%～142%; the relative deviation is 6.0%～13.8%. The method is simple, sensitive and can meet the trace detection requirements of 12 kinds of esters in water.
