“…The determination of aniline levels in soil mainly includes the pre-treatment of soil samples and the use of analytical instruments. For the analysis of aniline, earlier reported methods such as thin layer chromatography [ 11 ], spectrophotometry [ 12 ], micellar electrokinetic capillary chromatography [ 13 ], etc. [ 14 , 15 , 16 ] have been gradually replaced by modern advanced technologies due to their poor sensitivity and selectivity.…”

In this study, a rapid and simple method based on accelerated solvent extraction (ASE) combined with gas chromatography-mass spectrometry (GC-MS) was established to determine the levels of aniline in soil. The matrix spike recovery rates of aniline were investigated by changing several experimental parameters such as vacuum freeze-drying, accelerated solvent extraction, sample transfer, nitrogen-blowing concentration and solvent exchange. Under optimized pretreatment conditions, the linearity of the method ranged from 0.5 to 20 μg mL−1 for aniline, and the correlation coefficient was 0.999. Recoveries of aniline from quartz sand and soil ranged from 76% to 98%, while the precision was excellent with average inter-day and intraday values ranging (n = 6) from 3.1% to 7.5% and 2.0% to 6.9%, respectively. The limits of quantification of the method were 0.04 mg kg−1. Notably, the results show that the method we developed is simple, fast, low cost and can meet the requirements for the determination of aniline in soil samples, sewage sludge, river and pond sediments.

“…Several analytical methods were used for the analysis of aniline and its derivative products including thin layer chromatography, 22 spectrophotometry, 23 capillary electrophoresis, [24][25] micellar electrokinetic capillary chromatography, 26 and gas chromatography/mass spectrometry. 27 However, these methods are difficult and require a derivatization step and cleaning procedure.…”
