【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%。更多还原

【Abstract】 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 200 μg/L. The method detection limits were within 0. 7 μg/L ~ 1. 0 μg/L when the sample amount was 40 m L. Spiked recoveries in three real samples ranged from 81. 2% ~ 98. 0%. The RSDs of replicate measurement(n= 6) were less than 12%.更多还原
