Dioxin (Dioxin), also known as Dioxin, is a colorless, tasteless, teratogenic, fat-soluble substance, and is a generic name of Dioxins (Dioxins) in nature, which refers to aromatic organic compounds composed of two or one oxygen atom connecting two chlorine atoms substituted to benzene ring. Dioxin comprises 210 compounds, and the substances are very stable, have high melting points, can be dissolved in most organic solvents and are very easy to accumulate in organisms. Dioxin is a highly toxic substance 130 times that of cyanide and 900 times that of arsenic, and is called century toxicity. Analysis of dioxins generally employs the following steps: sampling, homogenizing, extracting, purifying, analyzing and evaluating data.
The concentration of dioxin in the environment is low, the components are complex, and a large number of interferents exist, and a sample can be used for gas chromatograph-mass spectrometer analysis only by four-stage purification after being subjected to homogeneous extraction and enrichment. The purification of the dioxin sample is divided into four stages, wherein the first stage is an acid silica gel purification column to remove lipid, reducing compounds and polycyclic aromatic hydrocarbon in the sample. The second stage is a Florisil silica purifying column which removes non-planar PCBs, biphenyls, chlorobenzene, phenols, PAHs, DDE and other non-polar or medium-polar compounds in the sample, and the third and fourth stages are activated carbon purifying columns which remove the non-polar compounds in the sample.
