NOVELTY - Treating acidic arsenate-containing wastewater comprises preparing aqueous solution of fumed graphene and aqueous solution of iron(III) chloride, and coagulating to obtain graphene oxide-iron precipitate; mixing separated graphene oxide-iron precipitate with treated acidic arsenate-containing wastewater to obtain graphene oxide-iron(III) arsenate precipitate; and mixing isolated graphene oxide-iron(III) arsenate precipitate with alkali solution to recover graphene oxide. USE - Method for treating acidic arsenate-containing wastewater (claimed). ADVANTAGE - The method has good application prospect. It produces high adsorption efficiency of arsenate, realizes regeneration and recycling of oxidized graphene, and reduces cost.
