This research studies the optimization of pretreatment methods and standard curve configuration of 12 aniline com-pounds in soil via ultrasonic extraction,liquid chromatography-triple quadrupole mass spectrometry,confirmed the pre-treat-ment conditions such as ultrasonic extraction,centrifugation and concentration,method feasibility was verified by actual sam-ples determination.The results show that by conducting the optimized sample pretreatment methods and standard curve config-uration,the correlation coefficient of compound are higher than 0.999,except for 2,4-dimethylaniline and p-Nitroaniline cor-relation coefficients are greater than 0.995.The detection limits of 12 aniline compounds were 1～4 μg/kg,the relative stand-ard deviations of low,medium,and high blank spiked samples were 1.5％～7.3％,and the recoveries were 76.2％～110％.The method has clear conditions,simple operation,and can improve the accuracy and efficiency of soil sample detection.
