| titleOfInvention | A kind of ammonium-modified alkaline birnessite restoration material and its preparation method and application |
| abstract | The invention discloses an ammonium-modified alkaline birnessite restoration material, a preparation method and application thereof. The method comprises: adding manganese chloride and ammonium chloride into water, mixing evenly to obtain a mixed solution; adding sodium hydroxide solution into the mixed solution, feeding oxygen into the mixed solution under stirring, centrifuging, washing, drying, and grinding into a powder, and sieved to obtain the ammonium-modified alkaline birnessite restoration material. The method mainly uses oxygen to reduce Mn(OH) 2 under a mixed medium of strong alkalinity and ammonium chloride to obtain ammonium-modified alkaline birnessite. The ammonium-modified alkaline birnessite restoration material provided by the present invention can be applied to the wastewater treatment of heavy metal As(Ⅲ), and the ammonium-modified alkaline birnessite restoration material is compared with unmodified alkaline birnessite The method can quickly and efficiently oxidize As(Ⅲ) to As(Ⅴ), has good toxicity reduction and removal effect, no secondary pollution, is green and environment-friendly, and the preparation method of the material is simple. |
