摘要
利用大口径毛细柱气相色谱 /电子捕获检测器 (GC/ECD)气液平衡法测定饮用水中的三氯甲烷和四氯化碳。此方法简便、快速、灵敏度高 ,并具有较好的精密度与准确度。样品加标回收率为 86 %～ 10 2 % ,精密度为 0 9%～ 1 8%。
The volatile CHCl 3 and CCl 4 in drinking water have been determined by wide bore capillary gas chromatography/electron capture detector (GC/ECD) with gas liquid balance method. The method is simple, fast and highly sensitive. It has better accuracy and precision. The standard recovery range from 86% to 102%. And the precisions range from 0 9% to 1 8%.
