| 摘 要： | 以有机-无机混酸溶液为介质用电化学法制备了膨胀石墨，并用扫描电子显微镜(SEM)观察其表面形貌，膨胀后的石墨具有丰富的网络状结构，形成吸附油的储存空间。膨胀石墨对重油的吸附量随着膨胀容积的增大而增加，合适的电流密度、电解液浓度以及反应时间是制备高膨胀容积膨胀石墨的关键。

| Abstract: | Expandable graphite is prepared in inorganic-organic mixing acid solutions by electrochemical method in this paper. Surface micrograph of expandable graphite is studied using SEM. Plenty of network structure is viewed,which is the base of adsorption performance. Adsorption quantity increases with the expanded volume. Appropriate current density,electrolyte concentration and reaction time are the keys to obtain high-expanded volume. |
