摘要
建立了吹扫捕集-大口径毛细管柱气相色谱法同时测定饮用水和地表水中5种挥发性卤代烃和4种氯苯类污染物的方法,可不经有机溶剂萃取和浓缩,减少了沾污和损失,具有灵敏度高,受干扰因素少,定量准确,操作简便等特点。进样量为5mL时,检测限可达ng/L级,适合饮用水及地表水中低含量卤代烃和氯苯类污染物的测定。
The five kinds halohydrocarbons and chlorobenzenes were determined using Purge and Trap-GC in the same time. It can be extracted and concentrated without organic solvent to induce pollution. This method was sensitive, accurate and operation-simple. When the sample range was 5 mL, the detection limit was up to ng/L. It is suit to determine the low concentration halohydrocarbons and chlorobenzenes in drinking water and surface water.
