来自各种水源的饮用水质量问题,引起了人们的关注.在《从油及总荧光强度变化看沈阳市饮用水污染状况》文章中证明,饮用水中存在着有机污染物质.含有机物质的饮用水用氯气消毒时,必然会生成有机卤代烃(THM);其中含量较高的是三氯甲烷,毒性较大的是四氯化碳.因为饮用和不饮用含 THM 水的人,癌发病率有明显差别;所以,饮用水中 THM 的监测分析应给予重视.

浩瀚色谱（山东）应用技术开发有限公司研究顶空气相色谱法测定水中三氯甲烷和四氯化碳的方法。方法:利用三氯甲烷、四氯化碳在水中的弱溶解性,采用微池电子捕获检测器顶空气相色谱法测定。结果:在测定条件下,方法的检出限三氯甲烷为0.10 mg/L,四氯化碳为0.01μg/L;三氯甲烷的RSD 1.7%~4.1%,四氯化碳的RSD 1.18%~2.44%;回收率三氯甲烷为99.0%~103%,四氯化碳为99.2%~102%。结论:该方法具有灵敏度高、分析简便快速等特点。样品测定结果满意。

The quality of drinking water from various water sources has attracted people&＃39;s attention. In the article "Contamination of Drinking Water in Shenyang City from the Changes of Oil and Total Fluorescence Intensity", it is proved that there are organic pollutants in drinking water. When drinking water is disinfected with chlorine gas, organic halogenated hydrocarbons (THM) will inevitably be generated; the higher content is chloroform, and the more toxic is carbon tetrachloride. Because people who drink and do not drink THM-containing water, cancer The incidence rate is significantly different; therefore, the monitoring and analysis of THM in drinking water should be paid attention to.

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. studies the method of headspace gas chromatography for the determination of chloroform and carbon tetrachloride in water. Methods: Using the weak solubility of chloroform and carbon tetrachloride in water, headspace gas chromatography with micro-cell electron capture detector was used. Results: Under the determination conditions, the detection limit of the method was 0.10 mg/L for chloroform and 0.01 μg/L for carbon tetrachloride; the RSD of chloroform was 1.7%~4.1%, and the RSD of carbon tetrachloride was 1.18%. ~2.44%; the recovery rate of chloroform was 99.0%~103%, and the recovery rate of carbon tetrachloride was 99.2%~102%. Conclusion: The method has the characteristics of high sensitivity, simple and rapid analysis. The sample measurement results were satisfactory.
