Abstract

The invention relates to a method for detecting the content of anthracene and its oxides anthraquinone and anthrone in a multi-media environment. The method includes: (1) sample pretreatment; (2) instrument detection; the determination method of the present invention adopts GC-MS / MS to determine the content of anthracene, anthraquinone and anthrone in air, soil and water, and the method is simple to operate and has a detection limit of , recovery rate and precision all meet the requirements of environmental monitoring.

Description

technical field [0001] The invention relates to the technical field of detection of polycyclic aromatic hydrocarbon compounds, in particular to a detection method for the content of anthracene and its oxides anthraquinone and anthrone in a multi-media environment. Background technique [0002] Polycyclic aromatic hydrocarbons (PAHs) compounds are a class of persistent organic pollutants that are ubiquitous in the environment and have carcinogenic, teratogenic, and mutagenic effects. During the growth of crops, PAHs from multiple media such as air, soil and water will be enriched, which will cause food quality and safety issues and pose a threat to human health. Anthracene (Anthracene ANT, CAS No 120-12-7, C 14 h 10 ), widely used in industries such as dyes and pulp, mainly produced by incomplete combustion of fossil fuels such as petroleum and coal, and solid waste such as wood and tobacco. It is one of the 16 PAHs priority pollutants confirmed by the US Environmental Prot...
