The structure of graphite and graphite oxide was characterized by N 2 adsorption, X-ray diffraction (XRD) and Fourier transform infrared (FT-IR) spectroscopy. The results showed, that graphite does not show a significant change in surface area after the oxidation process. The layered of graphene structure were swelling, due to several oxygen functional groups were formed, which play a significant role in adsorption. The amount of Congo red adsorbed on the GO was much higher than on graphite which behave pseudo first order. The increase in the behavior of adsorption for graphite after oxidation was related to functional groups which causing electrostatic attraction.
