FIELD: chemistry.
SUBSTANCE: group of inventions relates to a method for reducing the presence in the environment of at least a portion of one or more environmental pollutants in a substance, a sorbent, as well as a method of producing a sorbent. Method is aimed at reducing the presence in the environment of at least a portion of one or more environmental pollutants in a solid substance, a liquid substance or substance, which is a combination of one or more solid substances and a liquid substance. Said combination contains one or more environmental pollutants. According to the method, a sorbent containing halogen and sulphur is added to said substance. Sorbent contains sulphur, one or more halogens selected from fluorine, chlorine, bromine and/or iodine, and one or more substrate materials.
EFFECT: halogen in sorbent is obtained from a source selected from elementary halogens, halogenated acids, halides of alkali metals, halides of alkali-earth metals and ammonium halides, thereby reducing the presence in the environment of at least a portion of one or more environmental pollutants in the substance.
