More Information
Summary:FIELD: oxidation catalysts and waste water treatment. ^ SUBSTANCE: catalyst than may be used in hydrogen peroxide-mediated oxidation of phenol in waste waters at 50-70°C is based on montmorillonite clay and iron and aluminum ions intercalated in the form of polyoxometallate cation [Al12FeO4(OH)24(H2O)12]7+. Complete oxidation of phenol into CO2 and H2O with hydrogen peroxide is effected in presence of above-defined catalyst, which is characterized by low degree of washing-out of active component into solution, at 50-70°C, preferably in aqueous solutions with acidity close to neutral. ^ EFFECT: reduced expenses, simplified preparation procedure, and achieved environmental safety. ^ 5 cl, 1 dwg, 3 tbl, 15 ex
