Description

technical field

[0001] The invention relates to a method for dechlorination of organic chlorine compounds. Background technique

[0002] Chlorinated organic compounds are an important class of compounds widely used in various chemical raw materials and reagents.

[0003] Among the numerous organochlorine compounds, some compounds are not only highly toxic, but also difficult to degrade in the environment, posing a threat to the ecological environment and human health. Of greatest concern are the potential hazards of persistent organic pollutants that are difficult to degrade. Among them, lindane, moxa reagent, di reagent, DDT, dioxins, polychlorinated biphenyls, and hexachlorobenzene have attracted special attention. Due to their long-term persistence, bioaccumulation, semi-volatility and high toxicity, these substances have been listed as persistent organic pollutants by the Stockholm Convention. It is of great significance to disinfect it.
