6-diethylaniline- 摘要:
- 提出采用顶空-气质联用法快速分析环境水体中的2，6-二甲基苯胺（DMA）、2，6-二乙基苯胺（DEA）和2-甲基-6-乙基苯胺（MEA）。在优化顶空条件的基础上，确定了最佳实验条件：以氢氧化钠作为基体改进剂，基体改进剂添加量为3.0 g，顶空平衡温度为80 ℃，顶空平衡时间为40 min。结果表明，该方法可以有效分离水样中的DMA、DEA和MEA，在0~200.0 μg/L范围内具有良好的线性关系（r2≥0.998），方法的检出限在0.30~0.41 μg/L之间，加标回收率在77.4%~110.6%之间，相对标准偏差（n=8）在3.8%~11.6%之间。该方法具有操作简单快速、精密度和准确度良好等优点，适用于环境水体中DMA、DEA和MEA的同时快速测定。
- Abstract:
- This paper proposed a headspace GC-MS method for rapid determination of 2,6-xylidine (DMA), 2,6-diethylaniline (DEA) and 2-methyl-6-ethylaniline (MEA) in environmental water. Based on the optimization of headspace conditions, the optimal analytical conditions were determined as follows: sodium hydroxide was used as the matrix modifier, the dosage of matrix modifier was 3.0 g, the headspace equilibrium temperature was 80 ℃ and the headspace equilibrium time was 40 min. The method effectively separated DMA, DEA and MEA from the water samples, and had a good linear relationship (r2≥0.998) in the range of 0-200.0 μg/L. The detection limit of the method was 0.30-0.41 μg/L, the recovery rates was in the range of 77.4%-110.6%, and the relative standard deviation (n=8) was between 3.8% and 11.6%. The method has the advantages of simple and rapid operation, good precision and accuracy, and is suitable for simultaneous determination of DMA, DEA and MEA in environmental water.
