Adsorption has been regarded as the most promising approach for the elimination of fluoride contamination owing to its cost-effectiveness and high efficiency. Nanomaterials are excellent adsorbents for defluoridation due to their high specific surface area, high adsorption properties, and ease of self-assembly. However, there are still some challenges in the application of nanoadsorbents for wastewater treatment. Therefore, this review summarizes the research progress of nanoadsorbents for fluoride removal and develops a fundamental understanding of the structure and adsorption properties of nanoadsorbents in different dimensions. It studies the synergistic effects of different nano- components in adsorption capabilities. In addition, challenges related to the engineering applications of nanoadsorbents and some suggestions to address these issues are presented to promote their practical application prospects.KEYWORDS: Adsorptionfluoridenanoadsorbentswater remediation ACKNOWLEDGMENTSThis work was financially supported by the National Natural Science Foundation of China (NO. 52170096) and the Major Projects of Erdos Science and Technology (2022EEDSKJZDZX015) and the Fundamental Research Funds for the Central Universities (NO.2022YJSHH07).DISCLOSURE STATEMENTNo potential conflict of interest was reported by the author(s).AUTHOR CONTRIBUTIONSWenjing Lu: Conceptualization, methodology, investigation, resources, writing-original draft, writing-review & editing.

To answer the growing clinical demand, fast, reliable and efficient purification methods to isolate copper isotopes from the irradiated target materials used for their production were developed. Chromatographic techniques have been extensively studied and used to isolate copper isotopes from other metals such as nickel, zinc, or cobalt. This review comprehensively surveys the ion exchange and extraction chromatographic methods developed for copper radioisotope purification to produce radiopharmaceuticals for medical use. Key factors such as target material, isotopic enrichment, number of steps and clinical application are discussed.

Polysaccharide hydrogels with controlled release of nutrients have been developed to minimize nutrient leaching and run-off. This review compares the loading and release of different nutrients from polysaccharide hydrogels for fertilizing purposes. Urea was encapsulated into polysaccharide hydrogels through blending, adsorption, and coating to minimize fast hydrolysis and possible volatilization. Urea release could be controlled by incorporating inorganic fillers, increasing polymer density, and reducing pore size. Early works incorporated polysaccharides into synthetic polymer hydrogel. Cellulose, cellulose derivatives, starch, chitosan, and alginate were later used as the composite hydrogel in urea encapsulation. The controlled release of other nitrogen sources such as KNO3, NH4NO3, NH4Cl, and leather waste was also studied. Phosphate release was reduced using copolymers containing Arabic gum, carboxymethyl cellulose, and starch-rich waste besides chitosan and carboxymethyl cellulose hydrogels. Potassium release from polysaccharide hydrogel containing nitrogen, phosphorus, and potassium could be electrostatically controlled. Polysaccharide hydrogels containing micronutrients, humic acids, and sucrose were also developed. Most of the polysaccharide hydrogels did not fulfill the nutrient release standards. Besides controlling the release of multiple nutrients, further reduction of cost using polysaccharide-rich waste and nutrients in the wastewater should be considered.KEYWORDS: Polysaccharidehydrogelnutrientcontrol releasefertilizer DISCLOSURE STATEMENTNo potential conflict of interest was reported by the author(s).Additional informationFundingThis work is funded through Engineering X, an international collaboration funded by the Royal Academy of Engineering and Lloyd’s Register Foundation.","PeriodicalId":49539,"journal":{"name":"Separation and Purification Reviews","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135883198","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this review article, literature on simulations of physically surface-patterned membranes is reviewed, with emphasis on the various factors affecting their anti-fouling performance. Associated computational techniques, including computational fluid dynamics and Brownian dynamics, are discussed. Key parameters discussed in the literature include the dimensions of the membrane (height, width), the velocity and direction of the fluid flow, the size of the particles, and the pattern size (height, width, and pitch). The key observables are the shear stress and velocity streamlines at various points, especially the pattern apex and valley regions, with an un-patterned membrane as a point of comparison in studies. The review concludes that the pattern dimensions have the most significant influence on the anti-fouling performance. Also, the effect of particle size to membrane pattern ratio on the extent of particle deposition on the membrane (fouling activity) can be explained by understanding the shear stress distribution around the membrane.KEYWORDS: Patterned membraneanti-foulingsimulationComputational fluid dynamics (CFD)Brownian dynamics (BD) AcknowledgmentsDC is thankful to the Ministry of Education, India, for providing research fellowship.Disclosure statementNo potential conflict of interest was reported by the author(s).","PeriodicalId":49539,"journal":{"name":"Separation and Purification Reviews","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135095083","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
