These characteristics provide DES highly suitable for membrane applications. In this study, cellulose acetate (CA) membrane is fabricated using DES. The DES is prepared by mixing thymol (Thy) and decanoic acid (DA). CA is dissolved in the DES and the solution is casted into a film to fabricate non-porous membranes by phase inversion method. To find the optimum solvent for CA, various types of DES are tested with different compositions of which Thy and DA, both naturally occurring chemicals, are selected. Variations in membrane structure and performance are also analyzed by altering the ratio of Thy to DA. Additionally, it is confirmed that DES is completely removed during the phase inversion process after casting the CA dope solution, demonstrating that DES functions solely as a solvent and not as an additive. The fabricated non-porous CA membranes are applied for dehydration of a water and isopropyl alcohol mixture via pervaporation. The membranes exhibit a high flux of 5.381 kg/m2·h and a selectivity of 16. Both DES and CA are biodegradable and biocompatible, yielding viable substitutes for the toxic and harsh organic solvents traditionally used in membrane fabrication.","PeriodicalId":427,"journal":{"name":"Separation and Purification Technology","volume":"1 1","pages":""},"PeriodicalIF":8.6,"publicationDate":"2025-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143560652","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recently, polyelectrolyte hydrogels have attracted considerable attention in the field of salt resistance owing to their electrostatic effect between the charged groups within the skeleton of hydrogel. The conventional polyelectrolyte hydrogels mostly use single-charged groups, limiting their ability to resist salt accumulation during prolonged operation. For solving this problem, we herein demonstrated self-healing as an effective method for binding anionic–cationic polyelectrolyte dual-layer hydrogels using dynamic covalent bonds of borax. Such design have minimized the amount of Na+ and Cl− ions diffusion into the hydrogel matrix and achieved exceptional salt-resistance, benefiting from electrostatic interaction between functional groups of the evaporator and salt ions. Additionally, the dual layers provided excellent thermal insulation, reducing the heat loss to surrounding water. Hereby the hydrogel evaporator achieved stable long-term performance with an evaporation rate of 2.43 kg m−2h−1 under 1sun irradiation. More importantly, no salt precipitation occurred on the solar absorber surface, even with varying salinities over more than seven days. All in all, the integration of anionic and cationic hydrogel layers achieved through the self-healing feature, significantly enhances the performance of interfacial steam generators used in seawater desalination applications.","PeriodicalId":427,"journal":{"name":"Separation and Purification Technology","volume":"59 1","pages":""},"PeriodicalIF":8.6,"publicationDate":"2025-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143560694","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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 work, a high-strength polytetrafluoroethylene (PTFE) substrate was used for interfacial polymerization (IP) to fabricate FO membranes. The innovative approach enhances membrane performance by improving hydrophilicity with surfactant modification to facilitate better water transport in FO. Dodecyl trimethylammonium bromide (DTAB) was added into the aqueous phase to control the IP process, and the optimized DTAB concentration was determined to be 70 mg L−1, which was labeled as PTFE-DTAB70 membrane. Characterization analysis showed that DTAB stabilized carboxyl groups in the PA layer through electrostatic interactions, inhibiting amide bond hydrolysis. After immersed for 60 days under extreme pH conditions (1–13), the membrane maintained high water flux (>16 LMH) and low reverse salt flux (<0.56 g L−1). Its chemical stability significantly surpassed that of commercial CTA membrane, with a 295 % increase in water flux at pH 13.

Coagulation/flocculation is simple, effective, and low-cost membrane pretreatment method. The performance of coagulation/flocculation, including its coupling processes with other pretreatment technologies, in controlling pressure-driven membrane fouling has been reviewed in detail according to fouling type (including inorganic, organic, and microbial fouling) in this paper. The development prospects of this technology are also explored to further improve its application performance. Coagulation/flocculation generally shows high efficiency in removal of insoluble inorganic, organic and microbial colloids in effluents by charge neutralization, bridging and sweeping effects to thus mitigate membrane fouling. For soluble matter, especially for low molecular-weight ones, the mitigation effect highly depends on the selected coagulant/flocculant, in addition to the coupling pretreatment technologies. A desired coagulant/flocculant can effectively bind to and transform the solute from hydrophilic to hydrophobic by some valid interactions, and cause an easy destabilization, aggregation and final formation of large and loose flocs. The resultant flocs can be trapped on the membrane and further form loose and porous cake layer, thus increasing membrane flux, decreasing membrane resistance, and alleviating membrane fouling. Based on an improved understanding of the membrane fouling and also coagulation/flocculation mechanisms at the molecular levels, designing and selecting an advanced coagulant/flocculant, with the advantages of high performance, environmental friendliness and low cost, is crucial to achieve the desired pretreatment effect","PeriodicalId":427,"journal":{"name":"Separation and Purification Technology","volume":"131 1","pages":""},"PeriodicalIF":8.6,"publicationDate":"2025-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143560691","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The direct electrocatalytic reduction of highly toxic As(III) to elemental arsenic (As(0)) in waste acid represents a promising green strategy for As removal. However, several obstacles remain to be overcome. In this study, we investigated the electrocatalytic reduction of As(III) to As(0) in simulated and real waste acid using an H-type cell at room temperature. The effects of diverse parameters, including cathode materials, potential, pH, and coexisting ions, on the reduction efficiency of As(III) to As(0) were examined. The selection of copper foam as the electrocatalyst was based on the findings of linear sweep voltammetry (LSV), cyclic voltammetry (CV), and electrochemical impedance spectroscopy (EIS). These measurements indicated that the Tafel slope and resistance of the copper foam were comparatively lower, thereby rendering it a suitable candidate for the desired application. The findings indicated that a lower pH was more conducive to the reduction of As(III), whereas the presence of co-existing cations impeded the reduction of As(III). The removal efficiency of As(III) was observed to reach 98 % within a 4 h period at an electrode potential of −1.25 V (vs. Hg/Hg2SO4) and pH 0.34. The XPS, SEM, and EDS results show that the solid precipitates are mainly composed of As(0) with a small amount of As(III). Electron paramagnetic resonance (EPR) analysis and radical scavenging experiments indicate that both direct electro-reduction and H• contribute significantly to the reduction of As(III). Our results provide a promising method for the direct removal and recovery of As(0) from nonferrous smelting waste acid.","PeriodicalId":427,"journal":{"name":"Separation and Purification Technology","volume":"50 1","pages":""},"PeriodicalIF":8.6,"publicationDate":"2025-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143560653","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, improving the mass transfer efficiency and catalytic activity of anode materials is essential for effective treatment. In this study, a NiAl-layered double hydroxide (LDH) intercalated MXenes composite anode (NiAl-LDH/MXenes) was developed via electrostatic self-assembly for the degradation of norfloxacin (NOR) and antimicrobial resistance genes (ARGs) in hospital wastewater. The insertion of NiAl-LDH sheets expanded the MXenes interlayer spacing, alleviated stacking, and reduced mass transfer distance. This intercalation strategy promoted electron transfer and •OH generation, enhancing catalytic activity and enabling efficient degradation of NOR and ARGs. Compared to NiAl-LDH and MXenes, the NiAl-LDH/MXenes composite exhibited a higher oxygen evolution overpotential (2.21 V vs. SCE) and lower energy consumption (0.003 kWh/m3), achieving 97.31 % NOR degradation in 120 min and 95.73 % DNA degradation in 90 s. The composite electrode also exhibited excellent performance in treating practical hospital wastewater, achieving 91.19 % NOR removal, significant ARGs removal (e.g., qnrA by 96.72 %), and effectively reducing pathogenic bacteria such as Duganella by 4.21 logs. Linear sweep voltammetry confirmed direct electron transfer in NOR degradation, while quenching experiments, EPR, and molecular probe assays elucidated the role of •OH in degrading NOR and DNA. DFT calculations revealed that •OH preferentially targets the piperazine ring and carboxyl groups of NOR, as well as the –OH and C=O/C-N sites of DNA. This study introduced a novel intercalation-based anode modulation strategy using NiAl-LDH/MXenes for the concurrent degradation of NOR and ARGs, offering a robust solution for wastewater treatment.","PeriodicalId":427,"journal":{"name":"Separation and Purification Technology","volume":"3 1","pages":""},"PeriodicalIF":8.6,"publicationDate":"2025-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143560690","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At 0.5–2.5 g/L, it sustained over 90 % cell survival after 24 h, confirming biocompatibility. The addition of disodium hydrogen phosphate improved NaZrP’s properties by increasing layer spacing, ion adsorption rate, and adsorption capacity. Adsorption followed pseudo-second-order kinetics and the Langmuir model, indicating monolayer adsorption. Chemisorption was the dominant mechanism, with ion exchange occurring under weakly alkaline conditions. NaZrP exhibited minimal glucose adsorption and negligible impact on solution pH. Its rapid and selective ammonia removal, combined with reusability and cell compatibility, makes it a promising solution for managing ammonia toxicity in large-scale cell cultures.
