Method for simultaneously determining pesticides and antibiotics in soil and marine sediments

The invention discloses a method for simultaneously determining pesticides and antibiotics in soil and marine sediments, which comprises the following steps of: firstly, extracting compounds in a purified soil sample or marine sediment sample by using an improved solid-phase extraction method, and taking supernate as a tested sample; then, analyzing the matrix matching standard solution by using an ultra-high performance liquid chromatography-tandem mass spectrometer, drawing a matrix matching standard curve by taking the peak area of the quantitative ion mass chromatogram of the compound as a vertical coordinate and the mass concentration corresponding to the compound in the matrix matching standard solution as a horizontal coordinate, and determining the linear range of quantitative determination of each compound; and finally, carrying out qualitative analysis on the tested sample by using an ultra-high performance liquid chromatography-tandem mass spectrometer to determine whether the target compound exist
