| titleOfInvention | Zerovalent iron reducing agent and preparation method and application thereof |
| abstract | The invention relates to the field of industrial wastewater treatment, and discloses a zero-valent iron reducing agent and a preparation method and application thereof. The preparation method includes the following steps: A1. Wetting and drying the source reducing agent with sodium persulfate solution, Then, the aniline monomer is deposited on the dried source reducing agent by chemical vapor deposition to obtain an intermediate; A2, the intermediate is pyrolyzed at high temperature under a protective gas atmosphere to form nitrogen-doped iron on the surface of zero-valent iron Carbon coating layer (CN), that is, a zero-valent iron reducing agent with a coating structure is obtained; wherein, the source reducing agent is nano-zero-valent iron or supported zero-valent iron. In the present invention, the method of in-situ formation of CN coating layer to activate zero-valent iron by adopting a vapor deposition-pyrolysis strategy makes the reduction activity of the obtained zero-valent iron reducing agent high; CN coated on the surface of zero-valent iron nanoparticles The coating layer can prevent the loss of iron species, improve the utilization rate and stability of zero-valent iron, and realize the continuous utilization of the reducing agent. |
