    摘要: A method of removing hydrogen peroxide from sulfuric acid includes the following steps: First step of pouring the sulfuric acid having 0.1 wt % to 10 wt % of hydrogen peroxide into a vessel. Second step of adding a catalyst containing copper and a copper compound to the vessel to undergo a reaction with the sulfuric acid to remove the hydrogen peroxide from the sulfuric acid, to generate heat, and to generate metal ions in the sulfuric acid. Third step of activating a cooling device to cool the vessel to a predetermined temperature range. Fourth step of adding hydrogen sulfide to the vessel to undergo a reaction with the metal ions to generate metallic sulfide and metal free sulfuric acid. Fifth step of purifying the metallic sulfide and the metal free sulfuric acid to obtain purified metallic sulfide and purified sulfuric acid as products.
