| titleOfInvention | The preparation method and applications of nano zero valence iron |
| abstract | The invention discloses a kind of methods for preparing nano zero valence iron comprising following steps: (1) in an inert atmosphere, polyethylene glycol and deoxygenated ethanol being added in the aqueous solution of ferrous salt, mix；(2) mixed liquor obtained by step (1) is mixed with the aqueous alkali containing boron hydride, carries out reduction reaction；(3) it after step (2) reduction reaction, is precipitated；(4) above-mentioned precipitating is dried in vacuo, obtains nano zero valence iron.This prepares the method for nano zero valence iron, and preparation process is simple, without load, is not necessarily to high-temperature calcination；The nano zero valence iron of preparation has large specific surface area, reactivity high and remediation efficiency height, energy fast degradation organic pollutant.Surfactant combines prepared nano zero valence iron that can significantly improve VOCs contaminated soil remediation efficiency.Repair easy to operate, condition is easy to control, and repairs that speed is fast, and energy consumption consumption is low. |
