  • Process for producing stable cupric hydroxide and basic cupric salts
    Patent number: 6596246
    Abstract: Stable copper hydroxide is prepared by removing ferrous ion from the beginning cupric solution. The ferrous ion is oxidized to ferric ion, and the ferric ion is precipitated by raising the pH of the solution to 3-4. The utilization of phosphate ion both increases the efficiency of oxidation and simultaneously precipitates ferric ion. A second raising the pH of the purified solution precipitates highly pure copper hydroxide that can be harvested.

  • Method for making colloidal cupric compounds and their uses
    Publication number: 20020136781
    Abstract: Stable copper colloid solutions are prepared from purified solutions of copper sulfate. The copper sulfate solution is purified by adding oxidizing agent and adding phosphoric acid or phosphate ion to precipitate iron or aluminum. Adjusting the pH yield a colloidal solution. A solid salt is made from the colloidal solution by mixing the colloidal solution with a water miscible organic solvent such as methanol or acetone. The copper colloidal solutions are shown to be effective fungicides against fusarium.
