摘　　要：采用Elite-5MS色谱柱气相色谱法和HTHG-PW15S色谱柱气相色谱法两种方法对水体中甲基汞进行测定,两种方法所测定的标准曲线线性相关性较好,准确度较高,均可用于水体中甲基汞的测定。其中Elite-5MS色谱柱气相色谱法适用于水体中浓度较高情况下甲基汞的检测,HTHG-PW15S色谱柱气相色谱法适用于水体中浓度较低情况下甲基汞的检测。Methylmercury in water was determined by Elite-5MS chromatographic column gas chromatography and HTHG-PW15S chromatographic column gas chromatography.The standard curve determined by the two methods had better linear correlation and better accuracy,which could be used for the determination of methylmercury in water.Among them,Elite-5MS chromatographic column gas chromatography was suitable for the detection of methyl mercury in the case of high concentration in water,and HTHG-PW15S chromatography column gas chromatography was suitable for the detection of methyl mercury in the case of low concentration in water.
