“…The pore changes from an asymmetrical structure to a sponge-like pore structure. Hence the importance of the solvent; also, this fact determines the mechanical properties of the final membrane, and the researchers found that the combination of two solvents improved the tensile strength a 48% [ 86 ]. Tan et al, 2022 prepared a porous fibrous membrane of bacterial cellulose/La(OH) 3 for phosphate removal.…”

Nowadays, membrane technology is an efficient process for separating compounds with minimal structural abrasion; however, the manufacture of membranes still has several drawbacks to being profitable and competitive commercially under an environmentally friendly approach. In this sense, this review focuses on bio-based polymeric membranes as an alternative to solve the environmental concern caused by the use of polymeric materials of fossil origin. The fabrication of bio-based polymeric membranes is explained through a general description of elements such as the selection of bio-based polymers, the preparation methods, the usefulness of additives, the search for green solvents, and the characterization of the membranes. The advantages and disadvantages of bio-based polymeric membranes are discussed, and the application of bio-based membranes to recover organic and inorganic contaminants is also discussed.

Polyacrylonitrile (PAN) is widely used in the preparation of ultrafiltration membranes. However, the hydrophilicity, thermal, and mechanical properties of the PAN ultrafiltration membrane are poor, limiting the applications in water treatment technology. In this study, the hydrophilic jute microcrystalline cellulose (MCC) is utilized as the modifier for the PAN membrane aiming to develop the ultrafiltration membrane with improved performance. The PAN/jute MCC ultrafiltration membranes with varying jute MCC contents are prepared using the phase inversion method and their structure and properties are systematically characterized. The results demonstrate that the hydrophilicity and thermal stability of the PAN membrane are enhanced. Under optimal conditions, compared with pure PAN membrane, the tensile strength and elongation at break of the membrane increase by 22.64% and 9.84%, respectively, and the water flux can reach 88 L/(m2 h), with the bovine serum albumin rejection ratio of 85%. The above results support that jute MCC can improve the performance of the PAN membrane significantly.
