METHOD OF OXIDIZING ORGANIC COMPOUNDS IN PRESENCE OF HYDROGEN PEROXIDE (VARIATIONS)

摘要

FIELD: waste disposal. ^ SUBSTANCE: invention relates to methods for oxidizing organic compounds, including toxic ones, in aqueous media in presence of hydrogen peroxide and can be used for treatment of waste waters from various productions or chemical laboratories. Method of oxidizing organic compounds in aqueous solutions in presence of hydrogen peroxide and catalyst based on solid-phase iron-containing aluminosilicates, wherein catalyst in the form of powder (particle size between 20 nm and 0.1 mm), granules (particle size at least 0.1 mm), or powder deposited on porous carrier or on activated carbon granules. Catalyst is preliminarily activated by treatment thereof with aqueous solutions of organic or inorganic acids. Hydrogen peroxide solution can be added to above-mentioned solution after every specified time intervals throughout the reaction period. ^ EFFECT: achieved full oxidation of organics and intensified oxidation process. ^ 21 cl, 23 ex
