海上溢油回收凝油剂研究进展

频繁的溢油事故会对海洋生态环境造成严重的污染，使用凝油剂（OGA）是一种优良的溢油回收方式。本文分析了凝油剂的发展历程，根据结构组成对凝油剂进行分类，此外，针对凝油剂的有效性问题，分析了一系列有效性评价实验与凝油回收技术，为建立科学合理的评价指标提供了参考方案。在凝油材料研究进展方面，列举相选择性有机胶凝剂、多孔基有机胶凝剂与实际溢油凝油材料的研究现状，明确了可降解天然吸附材料或凝油剂研究与应用的发展趋势。最后，从凝油剂的经济成本和应用技术出发，阐释了当前凝油剂的发展难点与下一步工作的研究重点。

Advances in oil gelling agents for oil spilled recovery

Frequent oil spill accidents have caused serious pollution to the marine ecological environment. Oil gelling agent (OGA) is an excellent oil spilled recovery technology. This paper reviews the development history of OGA and proposes a reasonable classification from the structure. Analyze a series of evaluation experiments for effectiveness issues and oil-gelling recovery technology in order to provide a reference scheme for scientific and reasonable evaluation indices. Then, for the research progress of OGA materials, this paper lists the current status of phase-selective organogelators, porous-based organogelators, materials for actual oil spill treatment. Degradable adsorption materials may be the trend of research and application of OGA. Finally, from the economy and technology, the current development difficulties and the next research focus of OGA are analyzed.
