【 摘 要 】

In this research, the chemical modification of graphite waste with CeO2was developed and characterized. Graphite waste was pretreated with mechanical to obtain the size 200 mesh (75 μm), and thermal methods at 110°C oven for 6 hours. Here, we demonstrate final properties of graphite before modification (GBM), activated graphite (GA) and graphite/CeO2composite with variation of 0.5, 1 and 2 g of CeO2(G0.5; G1; G2). The effect of CeO2concentration was observed. The presence of cerium in modified graphite samples (G0.5; G1; G2) were analyzed using SEM-EDX. The results show that the best surface area was found in G2 is 26.82 m2/g. The presence of CeO2onto graphite surface does not significantly increase the surface area of composites.
