摘要

建立了液液萃取-气相色谱质谱同时测定饮用水中24种SVOCs的分析方法。试验在中性条件下二氯甲烷萃取2次,脱水浓缩定容后,用GC-MS进行分析。该方法线性范围较好,回收率和检出限满足要求,具有较高的灵敏度和准确度。适合饮用水中SVOCs的检测分析。
        An effective method was developed and applied to determine 24 kinds of semi-volatile organic compounds in drinking water using gas chromatographymass spectrometry combined with Liquid-Liquid extraction.The samples was extracted twice under neutral conditions using dichloromethane as an extractant,, dehydrated and concentrated, and then analyzed by GC-MS. The linear range of the method is good, the recovery rate and detection limit meet the requirements, and the method has high sensitivity and accuracy. which is suitable for the detection and analysis of SVOCs in drinking water.
