| 中文摘要: |
| 采用微球硅胶键合C18固相萃取柱萃取水样中的3-甲基吲哚，并用气质联用法测定，方法在0 mg/L～10.0 mg/L 范围内线性良好，方法检出限为0.2 μg/L。空白水样3个质量浓度水平的加标回收率为89%～94%,7次测定结果的RSD为2.3%～6.9%。用该方法测定7个实际地表水样品，其中4个地表水样品检出3-甲基吲哚，地表水样的加标回收率为81.5%～97.0%。 |
| 英文摘要: |
| A method for determination of 3 methylindole in surface water was established by using SPE cartridge packed with C18 micro ball silica gel and GC/MS. The linear range were 0 mg/L～10.0 mg/L. The method detection limit was 0.2 μg/L, spiked recoveries of blank water were from 89% to 94%, the relative standard deviation of 7 samples were from 2.3% to 6.9% in precision and accuracy tests. The method was used to detect 7 environmental samples collected on surface waters, 3 methylindole in different levels was found in 4 surface water samples and spiked recoveries were 81.5%～97.0%. |
