NOVELTY - Preparation of reduced graphene oxide (RGO)/ferric oxide magnetic composite involves adding ferrous chloride tetrahydrate to graphene oxide dispersion liquid, stirring to dissolve, dripping aqueous ammonia at room temperature to create alkaline environment, reacting for 15 minutes, centrifuging to obtain solid sample, washing with ultrapure water and ethanol and freeze drying. USE - Preparation of reduced graphene oxide/ferric oxide magnetic composite for removing sulfides in water (all claimed). ADVANTAGE - The method is simple, easy to implement, provides reduced graphene oxide/ferric oxide magnetic composite which can converts the sulfide into stable element sulfur and sulfone organic compounds through adsorption and catalytic oxidation, avoids secondary conversion of the sulfate, so the sulfide is thoroughly removed, and the removal effect is not affected by the pH of the solution.
