| 中文摘要: |
| 采用便携式GC-MS测定水体中的苯胺，并对水样中离子强度和顶空分析的平衡时间进行优化。试验表明，苯胺在10.0 μg/L～200 μg/L范围内有较好的线性，r为0.998；方法检出限为5.8 μg/L；回收率为92.8%～96.7%；RSD为3.2%～8.6%。用54种VOCs混合标样对苯胺标液进行干扰试验，结果试验条件下苯胺与VOCs得到有效分离。 |
| 英文摘要: |
| A new method for portable gas chromatography coupled with mass spectrometry (GC MS ) was established in order to analyze aniline in water.Ion intensity in water and equilibration time of head space were optimized. Experiments showed that this method possessed good linearity(the aniline concentration was between 10.0 μg/L and 200 μg/L),
with the correlation coefficient 0.998.The method detection limit come to be 5.8 μg/L. The recoveries were between 92.8% and 96.7%,with the relative standard deviations between 3.2% and 8.6%.Interfere test was carried out for aniline standard solution by 54 kinds of VOCs mixed standard sample.Aniline and VOCs could be separated effectively. |
