摘要：

This paper investigates a synthesis of graphene oxide (GO) from industrial waste via leaching and modified Hummers method. In leaching process, most of the impurities were effectively removed by dissolving into 6 M HCl at 70 degrees C for 210 mins to produce 92.28 % purity graphite residue. Subsequently, GO was synthesis via modified Hummers method with a combination of concentrated H2SO4 and KMnO4. The result from XRD and FTIR analyses confirmed that GO was successfully synthesized. Additionally, a monolayer and multilayer GO with wrinkles surface was observed by TEM which evident the existence of GO surface morphology.
