| Abstract: |
| Objective To obtain the optimum experimental conditions for preparation of graphene oxide. Methods Mixed Oxide Nitrogen-3 (MON-3) and graphite were used as raw materials for the preparation of graphene oxide based on chemical oxidation potential and ultrasonic method. The products of graphene oxide were characterized by SEM and XRD. Results For preparation of graphite oxide, the optimal initial ORP range was 1700 - 1800 mV. The graphite and N2O4 ingredient ratio of 1:10 H2O2 dosage, low temperature pretreatment of 18 mL, KMnO4 consumption of 1.5 g, oxidation temperature of 30 ℃, and oxidation time of 120 min were the best process conditions. For preparation of graphene oxide, the dispersion solvent pH of 11, scattered power of 150 W, dispersing time of 40 min were the best process conditions of ultrasonic dispersion. Conclusion Preparation of graphene oxide with these process conditions is not only helpful to solve the conversion problem of large quantities of scrap nitro-oxidants, but also can prepare graphene oxide, which is a high value-added civil industrial product. |
