A technique of utilizing a sulfuric acid/peroxide liquid mixture, for example, its waste liquid material, is to be developed so that the waste liquid can be re-utilized and effectively applied to obviate the problem resulting from disposal. To this end, there is provided a method for utilizing a sulfuric acid/peroxide liquid mixture, for example, its waste liquid, in which peroxide in the sulfuric acid/peroxide liquid mixture is decomposed to render it possible to utilize the liquid mixture as sulfuric acid.
