Abstract
The invention discloses a method for water treatment by utilizing graphene oxide-catalyzed ozone. The method comprises the steps of adding graphene oxide into an ozone reactor containing to-be-treated water, utilizing ozone to aerate the to-be-treated water where the graphene oxide is added, and maintaining a stirring and ozone aeration state in the water treatment process. The to-be-treated water can be water containing pollutants such as oxalic acid and deet. The pollutants are degraded by utilizing hydroxyl free radicals which have high oxidization capability and are generated by the ozone and the graphene oxide in the reaction process. Compared with activated carbon and carbon nano tubes, the method for water treatment by utilizing graphene oxide-catalyzed ozone has the advantages of being high in catalysis capability and quick in oxidization speed. Besides, the specific surface area of the graphene oxide is large, the raw materials are easy to obtain, and the ozone contains rich oxygen-containing groups and is good in dispersion effect in water and chemical modificability.
