technical field

The invention relates to the technical field of pollution, in particular to a composition and its application in removing indoor dioxin pollution.

Background technique

Dioxin, also known as dioxin, is a colorless, odorless, highly toxic fat-soluble substance. Dioxin is actually an abbreviation of dioxins. It is not a single substance, but two types of organic compounds that contain many congeners or isomers with similar structures and properties. Dioxins include 210 kinds of compounds. These substances are very stable, have a high melting point, are extremely difficult to dissolve in water, and can be dissolved in most organic solvents. They are colorless and odorless fat-soluble substances, so they are very easy to accumulate in the body. Serious harm to human body.

Dioxins mainly come from the burning of industrial boilers, household cooking, cremated remains, vehicle exhaust, open burning of garbage, forest fires, and the use and production of chlorine-containing compounds such as bleaching powder. The industrial sources of dioxins are mainly oxygen-containing aromatic compounds, including polychlorinated dibenzodioxins, coplanar polychlorinated biphenyls, and polychlorinated dibenzofurans; their pollution is cumulative and persistent.
