6-diethylaniline- 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.
