Abstract
The present disclosure discloses an efficient and regenerable nano manganese remover, and a method for preparing same and application thereof, belonging to the technical field of wastewater treatment and reuse. The manganese remover of the present disclosure includes FeO, RGO, SiOand EDTA. The FeOnanoparticles are supported on the surface of the RGO, the SiOcoats the FeO, and the EDTA is grafted on the SiO. First, FeO-RGO is prepared. Then, a TEOS-ethanol solution is dropwise added, and the resulting mixture is allowed to react to obtain FeO@SiO-RGO composite particles. Finally, an EDTA-water solution is dropwise added to obtain the manganese remover. The manganese remover prepared in the present disclosure is magnetic, and the preparation process is simple and easy for industrial production. The nano manganese remover can quickly remove manganese in manganese-containing wastewater. A small amount of the manganese remover can achieve a large adsorption capacity. Further, the nano manganese remover can be separated from the manganese-containing wastewater quickly, thereby avoiding secondary pollution to the system.
