“…Ultrafiltration involves a pore size of 0.1 to 0.01 μm and is one of the most effective membrane separation processes for removing pollutants. The pore size for microfiltration involves 1–0.1 μm and nanofiltration involves 0.01–0.001 μm [ 56 ]. Another type of porous membrane is based on symmetry.…”

“…The selective adsorbent can remove 90% of nitrate and 98% of humic acid [114]. Kahloul et al (2023) prepared a hydrophilic ultrafilter membrane for humic acid removal using cellulose acetate and Keggin polyoxometalate. Cellulose acetate alone has low mechanical resistance and is sensitive to temperature.…”

“…The addition of polyoxometalate up to 15% improves membrane properties and has good performance in removing humic acid. Another advantage of this membrane is that humic acid adsorption does not depend on the pH of the environment; however, permeate flux retention is dependent on pH and decreases in an alkaline environment[56].Diverse methods are employed by the biocomposites discussed in the text to eradicate pollutants. Investigating the mechanism behind porous biocomposites aids in enhancing our comprehension of their efficiency in eliminating pollutants and in the preparation of analogous composites that exhibit similar effectiveness.…”

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.
