| titleOfInvention | Method for preparing nano copper powder by recovering copper by using etching solution |
| abstract | The invention discloses a method for preparing nano copper powder by recovering copper by using etching solution, which is characterized by comprising the following steps of: step S1, extracting the waste etching solution; step S2, back extraction; step S3, preparing microemulsion; step S4, electrodeposition; step S5, collecting nanometer copper powder; and step S6, drying and packaging. The invention also provides the nano copper powder prepared by the method. The method for preparing the nano copper powder by recovering copper by using the etching solution disclosed by the invention has the advantages of wide raw material source, low price, short flow and less equipment investment; the product has the advantages of easy control of morphology and particle size, high purity, high surface activity, large specific surface area and good dispersibility, and is suitable for continuous large-scale production. |
