| titleOfInvention | A reducing ion-exchange membrane for treating precious/heavy metal-containing wastewater and recovering high-purity metal elements, and its method and application |
| abstract | The invention belongs to the field of heavy metal treatment, and relates to a reducing ion exchange membrane for treating precious/heavy metal - containing wastewater and recovering high - purity metal elemental substances, a method and application thereof. The membrane is used as a reducing ion exchange membrane material. First, it is filled with sodium in a sodium ion-containing solution to make it into a highly reduced state, and then it is placed in a metal ion-containing wastewater to make the precious/heavy metal ions in the reducing ion exchange membrane. The surface is reduced to metal element, and the reduced metal element can be easily recovered. The method is simple in device, does not need to participate in the reduction process, the device design has high flexibility, does not need to consume a large amount of chemical reagents, uses clean electrical energy to reduce metal ions, has high selectivity to precious/heavy metal ions, and can It is very convenient to recover precious metals in elemental state. The prepared reducing ion exchange membrane material can still maintain good sodium storage performance after 50 cycles, and has excellent recycling performance. |
