Problems solved by technology

[0004] In addition, due to the complex composition of the soil, the recovery rate is only 65-93% and the standard deviation reaches 7-23% when LC is used for detection alone. Therefore, it is necessary to design a new test method to detect improve accuracy

Abstract

The invention discloses a method of analyzing polybrominated diphenyl ethers in soil by liquid chromatography-tandem mass spectrometry, which relates to the field of soil detection. The method is technically characterized in that liquid chromatography and mass spectrometry are used in a tandem mode; a standard spectrogram is obtained through standard solution testing and a standard curve of a target compound is drawn; then, a sample is preprocessed, and in the case of computer test, the standard spectrogram is combined to find out a target peak corresponding to a phase; and according to the standard curve, the concentration of the target compound is calculated. In the overall operation mode, the peak shape of the target compound is sharp, the response is strong, the instrument analysis time is short, the speed is fast and the testing accuracy is thus effectively improved.

Description

technical field [0001] The invention relates to the field of soil pollutant content testing, in particular to a method for analyzing polybrominated diphenyl ether compounds in soil by liquid chromatography tandem mass spectrometry. Background technique [0002] As a typical brominated flame retardant, polybrominated diphenyl ethers (PBDEs) mainly include three industrial products, pentabromodiphenyl ether, octabromodiphenyl ether and decabromodiphenyl ether. With the advantages of good combustion effect, it has been widely used in electronic appliances, textiles, transportation and other industries. However, PBDEs are refractory, fat-soluble and bioaccumulative at the same time. In recent years, they have been gradually controlled by legislation. Included in the list of supplementary persistent organic pollutants controlled by the Stockholm Convention, decabromodiphenyl ether was included in the list of three types of carcinogens by the International Agency for Research on ...
