NOVELTY - Preparation of highly-reducing magnetic graphite involves adding graphene oxide and ferrous chloride to a container, adding distilled water, heating to 90 degrees C for 30-45 minutes, obtaining suspension, adding 0.4-0.5 mol/L sodium hydroxide solution to the obtained suspension, heating to 90 degrees C for 30-40 minutes, cooling the resultant suspension to room temperature, separating magnetic nanomaterials, washing three times, and vacuum drying in oven for 24 hours. The mass ratio of graphene oxide and ferrous chloride is 40-50:100-120. USE - Preparation of highly-reducing magnetic graphite used in preparation of chromium(VI) adsorbent (claimed). ADVANTAGE - The method enables simple and economical preparation of highly-reducing magnetic graphite having excellent absorption property, and chromium(III) conversion rate, and enables reduction of chromium(VI) to nontoxic trivalent chromium. DETAILED DESCRIPTION - Preparation of highly-reducing magnetic graphite involves adding graphene oxide and ferrous chloride to a container, adding distilled water, heating to 90 degrees C for 30-45 minutes, obtaining suspension, adding 0.4-0.5 mol/L sodium hydroxide solution to the obtained suspension, heating to 90 degrees C for 30-40 minutes, cooling the resultant suspension to room temperature, separating magnetic nanomaterials, washing three times, and vacuum drying in oven for 24 hours. The mass ratio of graphene oxide and ferrous chloride is 40-50:100-120. The mass-volume ratio of graphene oxide and distilled water is 40-50:100 mg/mL. The mass-volume ratio of graphene oxide suspension and sodium hydroxide is 40-50:2.5 mg/mL. An INDEPENDENT CLAIM is included for use of highly-reducing magnetic graphite in preparation of chromium(VI) adsorbent.
