摘要
以硫酸为插层剂、过氧化氢为氧化剂,用化学法制备了膨胀石墨,分析了膨胀石墨对水面原油的吸附过程,测试了膨胀石墨对水面原油和齿轮油的最大吸附量。结果表明:膨胀石墨对水面原油和齿轮油的最大吸附量均与油的黏度和温度有关,最大吸附量随温度的升高而升高,随黏度的升高而降低。
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 ofoil. It increased with the increasing of temperature of oil and decreased with the viscosity of oil.
