Over the past decades, a large amount of petroleum pollutants has been released into the environment resulting from various activities related to petrochemicals. The discharge of wastewater with petrochemicals can pose considerable risk of harm to the human health and the environment. The use of adsorbents has received much consideration across the environmental field as an effective approach for organic pollutant removal. There is a particular interest in the use of biomass adsorbent as a promising environmentally-friendly and low-cost option for removing pollutants. In this article, we present a review of biomass-derived adsorbents for the removal of petroleum pollutants from water. The features of different adsorbents such as algae, fungi, and bacteria biomasses are summarized, as is the process of removing oil and PAHs using biomass-derived adsorbents. Finally, recommendations for future study are proposed.
在过去几十年中，与石化产品相关的各种活动导致大量石油污染物排放到环境中。含有石化产品的废水排放会对人类健康和环境造成相当大的危害风险。在环境领域，使用吸附剂作为去除有机污染物的有效方法已受到广泛关注。特别令人感兴趣的是，将生物质吸附剂作为一种有前景的环保且低成本的污染物去除选择。在本文中，我们对用于从水中去除石油污染物的生物质衍生吸附剂进行了综述。总结了不同吸附剂（如藻类、真菌和细菌生物质）的特性，以及使用生物质衍生吸附剂去除油类和多环芳烃的过程。最后，提出了未来研究的建议。
