摘要: |
建立了同时测定水中54种挥发性有机物(VOC<sub>s</sub>)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VOC<sub>s</sub>在0.50~40.00 μg/L质量浓度范围内线性良好,相关系数R<sup>2</sup>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VOC<sub>s</sub>的同时测定。 |

Abstract: |
An analytical method for simultaneous determination of 54 kinds of volatile organic compounds (VOC<sub>s</sub>) in water was established and optimized.The correlation coefficients of 54 kinds of VOC<sub>s</sub> 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. |
