| titleOfInvention | A kind of high mechanical strength magnetic strong base anion exchange resin and preparation method thereof |
| abstract | The invention discloses a high mechanical strength magnetic strong base anion exchange resin and a preparation method thereof, belonging to the field of resin materials. The preparation method is as follows: adding a traditional strong base anion exchange resin into a mixed solution of a ferric salt and a ferrous salt, and then mixing the resin adsorbed with the ferric salt with ammonia water, so that the resin structure contains ferric tetroxide nanometers. particle. Then, the resin containing ferric oxide nanoparticles is added to the alcohol solution in which the silane coupling agent is dissolved for reaction, so that the surface of the resin contains a dense silica coating layer, and a magnetic strong base with high mechanical strength is obtained. Anion exchange resin. The mechanical strength of the synthesized magnetic resin is significantly improved, the sphericity rate after grinding can reach more than 95%, and it has strong magnetic properties, high wet true density and sedimentation rate, and large strong base anion exchange capacity. In addition, the resin has a certain acid resistance and can be widely used in the removal of anionic pollutants in water and wastewater. |
