Abstract  

Chitosan aerogel has good biocompatibility, non-toxicity, easy degradation and other excellent properties, which can be used as an ideal green oil adsorbent to effectively solve the major problems of oil leakage and pollution. The researching progress of new petroleum adsorbents based on chitosan aerogel was reviewed. Firstly, the advantages and disadvantages of traditional oil treatment methods and oil absorbents were compared and the superiorities of chitosan aerogels as oil adsorbents were summarized. Then the synthesis and modification methods of chitosan aerogels and their advantage as petroleum adsorbents were analyzed and summarized. Finally, the problems existing in the current research and the future research direction were summarized and prospected.

Key words： petroleum treatment      petroleum adsorbent      chitosan aerogels      adsorption properties      circular utilization      environment-friendly
