| titleOfInvention | Method for removing lead ions in electrolytic copper foil electrolyte |
| abstract | The invention belongs to the technical field of copper electrolyte treatment, and discloses a method for removing lead ions in electrolytic copper foil electrolyte. The method can effectively reduce the lead ion content in the electrolyte in the electrolytic copper foil production process. Zirconium chloride is used as metal salt, terephthalic acid is used as an organic ligand, N, N-dimethylformamide is used as an organic solvent, a solvent method is adopted to prepare UiO-66, the UiO-66 is loaded on expanded graphite to be used as a filling material of an adsorption column, the adsorption column has good removal capacity for lead ions in copper electrolyte, and after the electrolyte flows through the adsorption column, the concentration of the lead ions in the electrolyte is reduced to be less than 0.1 mu g/ml. Due to the reduction of the concentration of lead ions in the electrolyte, the service life of the titanium-based iridium-tantalum oxide coating anode is effectively prolonged. |
