【摘要】：目的建立对生活饮用水中17种半挥发性有机物进行快速检测的方法。方法参照国家标准方法 GB/T 5750.9—2006,使用气相色谱仪/ECD检测器、毛细管柱将4种检测半挥发性有机物的国家标准方法同时应用于生活饮用水中17种半挥发性有机物的检测。仪器参数为进样口温度280℃;恒压20 psi;分流比15∶1;柱温160℃保持7 min,程序升温以12℃/min升至240℃保持8 min;检测器温度350℃。结果 17种半挥发性有机物的回收率为85%~98%,相对标准误差为1.7%~5.3%(n=6),最低检出浓度为0.000 1 mg/L。结论本方法具有快速、准确、节约能源、对环境污染小、技术含量高的特点,适用于突发水污染事件中半挥发性有机物的快速筛查测定,特别适用于生活饮用水质的检验分析。
[Abstract]:Objective to establish a rapid method for the rapid detection of 17 kinds of semi volatile organic compounds in drinking water. Methods referring to the national standard method GB/T 5750.9 - 2006, using the gas chromatography /ECD detector and capillary column, 4 national standard methods for detecting semi volatile organic compounds were applied to 17 kinds of semi volatile organic compounds in drinking water. The instrument parameters were inlet temperature 280 C, constant pressure 20 psi, split ratio 15: 1, column temperature 160 centigrade, 7 min, programmed temperature rise from 12 /min to 240 /min, 8 min and detector temperature 350 degrees centigrade. Results the recovery of 17 kinds of semi volatile organic compounds was 85%~98%, the relative standard error was 1.7%~5.3% (n=6), and the lowest detection concentration was 0.0001 mg/L. Conclusion this method is fast, accurate, energy saving, environmental pollution and high technology content. It is suitable for rapid screening and determination of semi volatile organic compounds in sudden water pollution events, especially for drinking water quality.

【正文快照】： 随着社会的迅速发展,人类在生产实践活动中对有毒、有害有机物的使用量越来越大,由于不合理排放以及不适当处理,水体已遭受不同程度的有机物污染[1-5]。这些有机物可引起各种健康问题,甚至致癌、致畸、致突变等[6-7]。由于生产管理不善及运输等原因,在生产、运输和使用过程中
