The increasing awareness of the importance of a clean and sustainable environment, coupled with the rapid growth of both population and technology, has instilled in people a strong inclination to address the issue of wastewater treatment. This global concern has prompted individuals to prioritize the proper management and purification of wastewater. Organic pollutants are very persistent and due to their destructive effects, it is necessary to remove them from wastewater. In the last decade, porous organic polymers (POPs) have garnered interest among researchers due to their effectiveness in removing various types of pollutants. Porous biopolymers seem to be suitable candidates among POPs. Sustainable consumption and environmental protection, as well as reducing the consumption of toxic chemicals, are the advantages of using biopolymers in the preparation of effective composites to remove pollutants. Composites containing porous biopolymers, like other POPs, can remove various pollutants through absorption, membrane filtration, or oxidative and photocatalytic effects. Although composites based on porous biopolymers shown relatively good performance in removing pollutants, their insufficient strength limits their performance. On the other hand, in comparison with other POPs, including covalent organic frameworks, they have weaker performance. Therefore, porous organic biopolymers are generally used in composites with other compounds. Therefore, it seems necessary to research the performance of these composites and investigate the reasons for using composite components. This review exhaustively investigates the recent progress in the use of composites containing porous biopolymers in the removal of organic pollutants in the form of adsorbents, membranes, catalysts, etc. Information regarding the mechanism, composite functionality, and the reasons for using each component in the construction of composites are discussed. The following provides a vision of future opportunities for the preparation of porous composites from biopolymers.
人们越来越意识到清洁和可持续环境的重要性，再加上人口和技术的迅速增长，使人们强烈倾向于解决废水处理问题。这一全球关注促使人们将废水的妥善管理和净化作为优先事项。有机污染物非常持久，由于其破坏作用，有必要将其从废水中去除。在过去十年中，多孔有机聚合物（POPs）因其在去除各种类型污染物方面的有效性而引起了研究人员的兴趣。多孔生物聚合物似乎是POPs中的合适候选者。可持续消费和环境保护，以及减少有毒化学品的消耗，是在制备有效复合材料以去除污染物时使用生物聚合物的优点。含有多孔生物聚合物的复合材料与其他POPs一样，可以通过吸附、膜过滤或氧化和光催化作用去除各种污染物。尽管基于多孔生物聚合物的复合材料在去除污染物方面表现出相对良好的性能，但其强度不足限制了其性能。另一方面，与包括共价有机框架在内的其他POPs相比，它们的性能较弱。因此，多孔有机生物聚合物通常与其他化合物一起用于复合材料中。因此，研究这些复合材料的性能并探究使用复合成分的原因似乎很有必要。本综述详尽地研究了含有多孔生物聚合物的复合材料在以吸附剂、膜、催化剂等形式去除有机污染物方面的最新进展。讨论了有关机理、复合功能以及在复合材料构建中使用每种成分的原因的信息。以下内容展望了由生物聚合物制备多孔复合材料的未来机遇。
