▎ 摘  要

NOVELTY - Treating waste sulfuric acid from a graphene producing process, comprises: collecting the waste sulfuric acid; filtering; depositing to obtain a transparent sulfuric acid waste; then adding water to dilute the transparent sulfuric acid waste to obtain a solution of dilute sulfuric acid; and obtaining calcium sulfate crystals using the diluted sulfuric acid. USE - The method is useful for treating waste sulfuric acid from a graphene producing process (claimed). ADVANTAGE - The method is capable of economically, simply and easily treating the waste sulfuric acid in an eco-friendly manner.
