Method for detecting dioxin substances in solid waste and application

The invention discloses a method for detecting dioxin substances in solid waste and application of the method, and relates to the technical field of pollutant detection. The content of dioxin in the solid waste is measured by adopting an isotope dilution method, the detection limit of an existing detection method can be effectively reduced by adjusting condition parameters of an analytical instrument, the accuracy and precision of the detection method are improved, meanwhile, the internal standard recovery rate is improved, a chromatographic column is improved and designed into a three-section type, connection is performed by utilizing a ground opening, and the detection efficiency is improved. The efficiency can be improved, the sampling device is improved, high-humidity flue gas can be prevented through heating treatment, and the accuracy and precision can be improved. The detection method can be widely used for detecting the content of the dioxin in the solid waste type fly ash solidified block, especially
