Detection and analysis method for determining aniline in soil

The invention discloses a detection and analysis method for determining aniline in soil. The detection and analysis method comprises the following steps in sequence: 1, collecting a sample; 2, pre-treating the sample; 3, preparing a standard solution; 4, drawing a standard curve; 5, selecting an ion scanning mode by the gas chromatograph-mass spectrometer for analysis; 6, quantification by an internal standard method: after analysis in the step 5, calculating the peak area of the sample solution according to the drawn chromatogram, calculating the concentration of the sample solution according to the standard curve in the step 3, and enabling a target object to have a good linear relation in the continuous measurement range of the 0-50mg/L standard solution; and calculating the detection limit according to the measured and configured 0.1 mg/kg blank standard soil, and calculating the precision and the accuracy by measuring soil samples with the concentrations of 0.25 mg/kg and 1mg/kg for seven times.
