Although many publications have emerged in recent years focusing on MOF-based MMMs, this review specifically emphasizes the improvement of MOF-based pervaporation membranes through the design of dimension of fillers and microstructure. The challenges encountered in MOF-based MMMs for pervaporation and the essential requirements for practical separation applications are addressed. A brief summary of strategies is provided for designing MOF-based MMMs with desired microstructure, macrostructure and multicomponent characteristics by using MOFs as fillers. The latest progresses in novel MOF-based MMMs with specific compositions, controllable pore structure and improved compatibility for recovery of organics are also displayed. The broad application prospects of MOF-based MMMs in pervaporation are introduced, including recovery of ethyl alcohol, butanol and other organics. Moreover, the challenges faced in the practical application of MOF-based MMMs for recovery of organics are presented and the promising future directions are outlined.</p></div>","PeriodicalId":100033,"journal":{"name":"Advanced Membranes","volume":"4 ","pages":"Article 100092"},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2772823424000034/pdfft?md5=c12b7e142d89e0394603d14eb285bb13&pid=1-s2.0-S2772823424000034-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139816206","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The current process uses ultrafiltration-based membrane technology, where a semi-permeable material selectively extracts chemicals, such as uremic retention products, or remove excess water from blood by retaining certain compounds based on their size. As sugars, fats, proteins, biomolecules, cells, and platelets move into and across the tubular membrane in the hemodialysis process, the surface of the membrane begins to foul, which leads to major operational challenges that include sharp pressure drops with increasing operation times. The design of membranes with enhanced biocompatibility and anti-fouling properties is one avenue to increase the lifespan of the membrane used while facilitating the device operation and limiting the stress and discomfort of patients. This review presents interfacial interactions between blood components and membrane materials used in hemodialysis. The discussion analyzes the impacts of the hemodialyzer module design, membrane material morphology and surface chemistry on the long-term operation and performance of the hemodialyzers.

As some brine sources contain a higher ratio of Mg²⁺ ions to Li ​⁺ ​ions, Mg²⁺/Li⁺ separation becomes essential to improve extraction efficiency. Multiple membrane technologies were utilized in this application, including electrodialysis, membrane capacitive deionization, and nanofiltration (NF). Among the different technologies, NF membranes fabricated through interfacial polymerization have gained interdisciplinary attention due to their ease of modification, relative simplicity, and cost-effectiveness. Despite that, there are still multiple challenges in Mg²⁺/Li⁺ ​separation such as high Mg²⁺/Li⁺ ratio (MLR), trade-off between Mg²⁺/Li⁺ separation factor and pure water permeance (PWP), membrane fouling, and optimal working pH. To address these challenges, this review summarizes different nanofillers used to enhance the NF membrane performance, including carbon-based nanofillers, and polyhedral oligomeric silsesquioxane (POSS). Additionally, different NF membranes were categorized based on the modification to the interfacial polymerization, such as types of aqueous monomer, addition of nanofillers in aqueous phase, addition of nanofillers in substrate, addition of an extra layer within the membrane, and other modifications. Lastly, perspectives on the factors that affect the separation performance of the NF membranes including surface zeta potential, feed pH, pore size, hydrophilicity, and MLR will be discussed. It is anticipated that this comprehensive review can provide insights into the current progress of various modification strategies on NF membranes to drive future research and development of Mg²⁺/Li⁺ separation using this technology among the community.</p></div>","PeriodicalId":100033,"journal":{"name":"Advanced Membranes","volume":"4 ","pages":"Article 100093"},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2772823424000046/pdfft?md5=3d909d7205e0ba43c2e2ba0672b39caf&pid=1-s2.0-S2772823424000046-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140088191","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
