titleOfInvention | A zero-valent iron agent modified by aromatic carboxylic acid and its preparation method and application |
abstract | The invention discloses a method for preparing a zero-valent iron agent modified by an aromatic carboxylic acid. The method comprises: under normal temperature conditions, using an aqueous solution of an aromatic carboxylic acid as a solvent, adding a zero-valent iron agent to the solvent, and complexing After the reaction, the zero-valent iron agent modified by aromatic carboxylic acid is separated; or, sodium borohydride and vulcanizing agent are added sequentially or simultaneously to the ferric salt and/or ferrous salt, and the reduction reaction and vulcanization reaction are carried out, and the aromatic carboxylic acid is separated and obtained. Sulfurized nano zero-valent iron modified by family carboxylic acid. The present invention adopts the iron oxide, iron sulfide or iron nitride on the surface of the zero-valent iron agent modified by the aromatic carboxylic acid to complex with the carboxyl functional group in the aromatic carboxylic acid, thereby inhibiting the passivation of the zero-valent iron, thereby enabling Release more electrons to degrade pollutants and improve degradation efficiency. |
