摘　　要：建立气相色谱-质谱联用法(GC-MS)测定水体中一氯乙酸、二氯乙酸、三氯乙酸和一溴乙酸4种卤乙酸的方法,分析了内标物的选择,硫酸用量,水浴时间和温度,硫酸钠用量对测定的影响,确定了最佳实验条件.结果表明,该方法检测的灵敏度较高(ρmin>1μg/L),可广泛用于水体中卤乙酸的检测.In this study, the analysis method of 4 HAAs：MCAA,DCAA,TCAA,MBAA by GC-MS was found with GC-MS method firstly. Secondly, determination effects were investigated in the selection of internal standard substance, dosage of sulfuric acid and sodium sulfate, water bath hours and temperature, And then, optimum experiment condition was confirmed. Results show that method has high sensitivity of 1 ug/L minutes value, and can be widely used in HAAs testing in water body.
