摘要:

建立了同时测定水中54种挥发性有机物（VOCs）的吹扫捕集-气相色谱-质谱联用法，并对吹扫捕集条件进行了优化。优化后的方法，54种VOCs在0.50~40.00 μg/L质量浓度范围内线性良好，相关系数R2均＞0.995 6，检出限为0.021~0.105 μg/L，加标回收率为76.4%~110.8%，相对标准偏差为2.33%~15.8%。该法操作简单，消耗费用低，分析速度快，具有良好的灵敏度、回收率和重现性，能够满足生活饮用水中54种VOCs的同时测定。

Abstract:

An analytical method for simultaneous determination of 54 kinds of volatile organic compounds (VOCs) in water was established and optimized.The correlation coefficients of 54 kinds of VOCs were good in the range from 0.50 to 40.00 μg/L, and the detection limits ranged from 0.021 to 0.105 μg/L,the average recovery was among 76.4% to 110.8% with the relative standard deviation of 2.33%~15.8%.The method is simple operation,low cost consumption, fast analysis speed, good sensitivity, recovery and reproducibility.
