Abstract Graphene oxide (GO) was prepared by chemical oxidation-sonicated crushing method with flake graphite, sulfuric acid and potassium permanganate as raw materials. The prepared GO was characterized by means of spectroscopy SEM, laser granulometer, FT-IR, UV-vis and AFM. The results show that the few-layered GO could be differentiated from the multi-layered graphite oxide in a solution of the mixture of the two by observing the variation of the intensity and the profile of absorption peaks around 230 nm in the UV-vis spectroscopy. Based on this phenomenon, the qualitative and quantitative analysis of graphene oxides in the solution can be realized. Thereby the optimal conditions for the preparation of graphene oxide can be obtained. It is proposed that the appearence of multi absorption peaks nearby 230 nm in the UV spectra of GO may be attributed to the existence of a peculiar structure of discontinues p-p* conjugated system in the graphene oxide.
