Abstract
A method and an apparatus for recycling waste sulfuric acid solution are provided. The method includes providing a reaction tank and introducing a waste sulfuric acid (H2SO4) solution into the reaction tank, and the waste sulfuric acid solution includes hydrogen peroxide (H2O2). The method also includes supplying a compound containing chlorine into the reaction tank. The method further includes mixing the compound containing chlorine with the waste sulfuric acid solution to promote a chemical reaction that decomposes the hydrogen peroxide (H2O2).
