| Abstract: | A series of expansible graphite were prepared by a chemical oxidation method using natural flaky graphite,sulfuric acid,nitric acid and potassium permanganate as raw materials.Effects of the dosage of inserting agent and secondary oxidant, the type of the secondary oxidant on the expand volume were investigated. Expanded graphite with representational pore structure was further used in dealing with wasted oil (diesel oil) and the sorption ability was compared with the common oil sorbent (absorbent cotton, activated carbon). The result indicated that the sorption of expanded graphite is superior to common sorbent, and the bigger the expand volume, the superior the sorption is. |
