摘要
采用气相色谱-质谱联用法测定水中9种卤代乙酸类化合物,通过优化试验条件,使方法在5.00μg/L^200μg/L范围内线性良好。当取样量为40 m L时,方法检出限在0.7μg/L^1.0μg/L之间,3种实际水样的加标回收率为81.2%~98.0%,6次平行测定结果的RSD≤12%。
A method was established for determination of 9 kinds of haloacetic acids in water by GC-MS. The current method showed good linearity in the concentration range from 5.00 μg/L to 200μg/L. The method detection limits were within 0. 7 μg/L ～1.0 μg/L when the sample amount was 40 mL. Spiked recoveries in three real samples ranged from 81. 2% ～98. 0% . The RSDs of replicate measurement （ n = 6 ） were less than 12% .
