Abstract： |
Belonging to materials science field, the invention relates to an approach of producing recoverable oil pollution sorbent. Using expandable graphite as materials, expandable graphite sorbent can be obtained after quickly warming up to 400-1000deg.C. The sorbent has a super adsorptive capacity to oil matters. Deprivation efficiency is up to 90 percent in a short time and deprivation temperature can be in 21-60deg.C. The sorbent can be reclaimed and reused using combustion method and organic solvent to regenerate. Its adsorption and reclaiming treatment is simple and there is no pollution in treating process. |
