| 中文摘要: |
| 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5.00 μg/L~200 μg/L 范围内线性良好。当取样量为40 mL时，方法检出限在0.7 μg/L~1.0 μg/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%。 |
| 英文摘要: |
| 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 mL. Spiked recoveries in three real samples ranged from 81.2%~98.0%.The RSDs of replicate measurement(n=6) were less than 12%. |
