NOVELTY - Method for producing graphite oxide, involves (a) mixing graphite and an oxidizing agent to form a mixed powder, (b) kneading while adding a strong acid in portions to the mixed powder in a weight ratio of 0.5-7, (c) leaving a non-flowing kneaded product formed through kneading to oxidize the graphite to form graphite oxide, and (d) purifying the remaining oxidizing agent and strong acid. USE - The method is useful for producing graphite oxide. ADVANTAGE - The method reduces the amount of acid wastewater, and reduces the reaction time for preparing graphite oxide. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a graphite oxide prepared using the kneaded product, where the kneading is performed, and leaving the kneaded product formed through kneading to oxidize the graphite.
