Abstract: The expanded graphite was prepared by a chemical method, in which sulfuric acid acted as inserting agent and hydrogen peroxide was adopted as oxidant. The process of adsorbing the crude oil on seawater was analysed. The maximum adsorption capacities of the expanded graphite for crude oil and gear oil were measured. The results showed that the maximum adsorption capacities of the expanded graphite for crude oil and gear oil all were related with the temperature and viscosity of oil. It increased with the increasing of temperature of oil and decreased with the viscosity of oil.
