▎ 摘　　要

NOVELTY - The method involves centrifuging (S1) a reaction mixture after a high-temperature hydrolysis and oxidation stage in a graphene oxide preparation process, and reserving a set ratio of the total amount of the supernatant liquid and the lower solid to mix to obtain a sample. A sample portion of the samples is prepared (S2). The sample between a light source and a camera is put (S3), and a photo of the sample is taken. The superiority of the preparation process of graphene oxide is determined (S4), according to the content of graphite particles with incomplete oxidation exfoliation in the photo of the sample, the less the content of graphite particles with incomplete oxidative exfoliation, and the higher the superiority of the graphene oxide preparation process. USE - Method for detecting preparation process of graphene oxide. ADVANTAGE - The method can quickly determine the superiority of oxidation. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a detection system for the preparation process of graphene oxide. DESCRIPTION OF DRAWING(S) - The drawing shows a flow chart of the method for detecting preparation process of graphene oxide.
