Detection of Chloroform and Tetrachloromethane in Drinking Water by Using Solid Phase Microextraction Instrument

使用固相微萃取装置用气相色谱电子捕获检测器测定饮用水中氯仿和四氯化碳。测定结果表明 ,饮用水中氯仿和四氯化碳浓度与色谱峰面积呈线性相关 ,这是一种快速简便准确地测定饮用水中氯仿和四氯化碳的方法。

By using solid phase microextraction instrument,chloroform and tetrachloromethane in drinking water was detected in ECD of gas chromatography.The result reveal that the concentration of chloroform and tetrachloromethane in drinking water was in line with area of chromatography peak.This is a rapid and simplified accurate method for detection of chloroform and tetrachloromethane in drinking water.
