摘要
采用全自动监测系统测定长江饮用水源地中18种挥发性有机物，通过动态吹扫捕集气相色谱法快速分析水中的挥发性有机物（VOCs），18种有机物的方法检出限为0．07～0．50μg／L，在0～20μg／L范围内线性良好，混合标准溶液平行测定的 RSD＜10％，饮用水样品的加标回收率为72．1％～119．4％。同时，探索了4种监测数据质量控制及质量保证的方法，建立了数据评价体系。
Automatic determining system was used to determine 18 volatile organic compounds in drinking water source in the Yan-gtzeRiver.VOCs were determined quickly with the gas-stripping chromatographic method.The detection limits of 18 volatile organic compounds were between 0.07 and 0.50 μg/L,while the method had a good linearity in the range from 0 to 20 μg/L.The RSD of mixed standard solution was less than 10%.The spike recovery of drinking water samples was 72.1% ～119.4%.Four kinds of quality control and quality assurance in monitoring data were explored and the data evaluation system was established.
