Bio-adsorbents for water-oil separation

The ocean’s ecosystem and living organisms have suffered catastrophic harm as a result of crude oil leaks from containers, submersibles, oil refineries, and wells that severely pollute the environment. One of the biggest environmental issues facing the world today has recently gained significant public attention. The poisoning of the water and its inhabitants is another factor. The fishing and seafood industries have suffered greatly as a result, and millions of people now face health and life difficulties. There is currently no realistic and workable way to effectively reduce the harm caused by a crude oil spill. This has caught the interest of many researchers for creating a polymer adsorbent for cleaning up oil spills that is both affordable and environmentally benign. Recent research has shown that bio-based aerogel can be an excellent adsorbent for oil-water separation, which is a plausible alternative to the crude oil problem. In this chapter, bio-based aerogel adsorbents utilized in the field of water or oil separation are thoroughly examined. This covers techniques used to produce aerogel adsorbents, how they are synthesized, and how they are classified. The future orientation and technical development will also be extensively covered.
