Abstract:
A gas chromatography-triple quadrupole mass spectrometry coupled with solid phase microextraction method ( SPME-GC/QQQ) was developed for the determination of chlorinated anilines ( CAs) residues in soil. The multi-reaction monitoring ( MRM ) parameters were optimized. The SPME conditions such as amount of soil sample, volume of added water, extraction temperature and absorption time were investigated. Optimum SPME conditions including 8 g of soil sample, 4 mL of water, 80℃ of extraction temperature and 40 min of absorption time were employed in the experiment. Method detection limits were within the range of 1-10 pg/g, while linearities were within the range of 5-1000 pg/g. Under the optimized conditions, the soil samples spiked with 200 pg/g targets were determined with recoveries of 96. 8%-144. 2%and relative standard deviations of 13 . 4%-27 . 8% ( n=5 ) . The proposed method combines simplicity and rapidity of SPME and high selectivity of MRM. It is especially suitable for the quick screening and determination of trace amounts of chlorinated anilines residues in soil.
