摘要:

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0.07～0.50 μg/L，在0～20 μg/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。

Abstract:

Automatic determining system was used to determine 18 volatile organic compounds in drinking water source in the YangtzeRiver. 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
