Abstract
A method of electrochemical dissolution of ruthenium-cobalt (Ru—Co)-based alloy is disclosed, in which a Ru—Co-based alloy bulk is subjected into an electrolyte solution comprising about 50 wt. % to 75 wt. % of sulfuric acid, thereby electrolyzing the Ru—Co-based alloy bulk and forming a product solution comprising Ru and Co ions in the electrolyte solution.
Claims10
A method of electrochemical dissolution of ruthenium-cobalt (Ru—Co)-based alloy, comprising:
- providing an electrolyte solution, wherein the electrolyte solution includes 50 percent by weight (wt. %) to 75 wt. % of sulfuric acid;
- and
- subjecting a Ru—Co-based alloy into the electrolyte solution, thereby electrolyzing the Ru—Co-based alloy and forming a product solution, wherein the product solution comprises Ru ion and Co ion in the electrolyte solution.
