The aim of this study is to identify influence of different solvents on the properties of graphene oxide. In this work, Graphene Oxide (GO) was synthesized by treating graphite powder with KMnO4 and a mixture of concentrated H2SO4 and H3 PO4.The experiment is carried out at room temperature without NaNO3.The effects of reaction parameters such as reaction time, reaction temperature and amount of KMnO4 on the degree of oxidation of graphite powder to graphene oxide were studied. Graphene oxide powders prepared were dissolved into different solvents, namely acetone and ethanol. Both the samples were characterized by UV–Visible spectroscopy and FT-IR spectroscopy. The results showed that treating graphite powder with KMnO4 at 40oC for 12 h resulted in better degree of oxidation.
