The effect of different anions on dissolved organic matter (DOM) reactivity during the HCO process might vary considerably. However, the impact of this DOM conversion process induced by inorganic anions remains unclear. Herein, the effect of HCO₃⁻ and SO₄²⁻ on DOM molecular changes in petrochemical wastewater by HCO was systematically investigated using spectroscopy, resin fraction, and FT–ICR MS techniques. HCO₃⁻ showed stronger inhibition of organics on degradation than SO₄²⁻, primarily due to the scavenging of reactive oxygen species. Moreover, HCO₃⁻ and SO₄²⁻ favored the inhibition of hydrophobic fractions over hydrophilic fractions. At the molecular level, the similar effect of HCO₃⁻ and SO₄²⁻ on HCO favored the conversion of compounds with lignins/CRAM-like to aliphatic/proteins and aromatic structures. The higher reactivity of HCO + HCO₃⁻ with low-unsaturated and high-oxidized compounds resulted in reduced oxygen addition reactions. HCO + SO₄²⁻ promoted oxygen addition reactions due to facilitating the transformation of unsaturated DOM into more saturated aldehydes, ketones, and carboxylic acids. These findings highlight significant differences in HCO₃⁻ and SO₄²⁻ effects on DOM transformation during HCO. Our study provides molecular-level insights into the behavioral changes of DOM during HCO induced by inorganic anions, helping guide the optimization of HCO processes for treating actual industrial wastewater.</div></div>","PeriodicalId":427,"journal":{"name":"Separation and Purification Technology","volume":"375 ","pages":"Article 133808"},"PeriodicalIF":8.1,"publicationDate":"2025-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144170024","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, hydrophobic MOFs were initially identified using the Widom insertion method. Their features and separation properties calculated through molecular simulations were subsequently utilized as inputs for the development of machine learning (ML) models to identify the key factors that influence the performance of membrane-based C₂H₆/C₂H₄ separation. Based on ML insights, 11,973 hypothetical MOFs (hMOFs) were constructed, and 1229 hydrophobic hMOFs were further identified through a preliminary screening. The four high-performing hMOF membranes were further identified through precision screening, and hMOF-1 demonstrates effective C₂H₆/C₂H₄ separation under high humidity conditions, with performance comparable to that observed under dry conditions. Additionally, the gas separation mechanisms for high-performing hMOFs were also elucidated under both dry and humidity conditions.

The synergistic system (E-FeCo-N@SBE-PMS) was able to degrade PFOA with an efficiency of 93.12 % within 150 min. A column of FeCo-N@SBE material was characterized. The results showed that some Fe-Nx, Co-Nx and metal sites were observed. The presence of these sites further weakened the competitive reaction between simultaneously activated H₂O₂ and PMS and improved the synergistic efficiency of the E-FeCo-N@SBE-PMS system. Specifically, the Fe-Nx sites were prone to adsorb H₂O₂, which induced O-O bond breaking and ·OH formation. The Co-Nx sites had higher adsorption energies for PMS. It was more inclined to adsorb and activate PMS than the Fe-Nx sites. Electron Paramagnetic Resonance (EPR) and burst experiments demonstrated that the main active species of the coupled system were hydroxyl radicals (·OH) and single-line oxygen (¹O₂), while sulfate radicals (SO₄^·-) and other Reactive Oxygen Species (ROS) played a secondary role. FeCo-N@SBE improved the force of ·OH with perfluoroalkyl radicals (PFOA·) by highly selective electrogeneration of H₂O₂ and its in situ activation to generate ·OH. It is worth noting that the deprotonation of the FeCo-N@SBE under the action of 2e^--ORR contributes to the conversion of SO₄^·- to ·OH, which further modulates the enrichment of PFOA· near the cathode. The bound PFOA· forms a concentrated reactive zone with ROS to accelerate the degradation of PFOA. These results provide new insights into the rational design of an E-FeCo-N@SBE-PMS system constructed with modified cathodes and provide new theoretical support for the selective degradation of PFOA.","PeriodicalId":427,"journal":{"name":"Separation and Purification Technology","volume":"146 1","pages":""},"PeriodicalIF":8.6,"publicationDate":"2025-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144176782","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}

Herein, we propose a sustainable strategy for swine manure (SM) management by converting it in-situ into nitrogen-doped biochar via one-step pyrolysis at 750 °C (NBC750). The NBC750/peroxymonosulfate (PMS) system efficiently degraded organic pollutants, achieving complete tetracycline (TC) degradation with a reaction rate constant (<em>k</em>_obs) of 0.33 min⁻¹, surpassing most previously reported waste-derived heterogeneous catalytic systems. Notably, TC degradation was accelerated under specific environmental scenarios, particularly in the presence of HCO₃⁻ or at pH &gt; 9, highlighting its adaptability to alkaline and bicarbonate-rich environments. Mechanistic studies confirmed two synergistic pathways: (1) Electron transfer dominated by graphitic N (62 % contribution), identified as the primary route; and (2) Radical pathways (38 % contribution), where C=O/O-C=O groups activate PMS to generate ^•OH and SO₄^•−. The NBC750/PMS system demonstrated high potential in practical applications, as suggested by its robust anti-interference capability and stable performance across various water matrices.

In this work, we report a dual–function heterojunction of CdS/ZnO for visible light-driven photocatalysis assisted with adsorption, where CdS/ZnO-140 not only accelerates reaction kinetics but also enhances overall U(VI) removal efficiency by confining adsorbed U(VI) near catalytic sites. Furthermore, CdS/ZnO composites were prepared via a facile hydrothermal method, and the effects of hydrothermal temperature on U(VI) removal performance under visible light were systematically investigated. Compared with the pristine CdS and ZnO nanoparticles, the CdS/ZnO heterojunctions exhibit higher removal performances, attributed to the introduction of ZnO component that significantly improves both adsorption capacity and spatial separation efficiency of photo-generated electron-hole pairs. More importantly, different key factors including band gap, energy level, crystallinity, specific surface area, adsorption kinetics and radical generation amount were taken into account for structure–performance investigation of U(VI) photocatalytic removal. Notably, the CdS/ZnO-140 composite exhibits superior U(VI) removal efficiency, outperforming counterparts synthesized at 100 °C and 180 °C. The investigations reveal that the enhanced U(VI) removal activity of CdS/ZnO-140 could be correlated with the efficient charge separation and migration, carrier dynamics, and surface active sites. By elucidating the role of hydrothermal temperature in tuning carrier dynamics and surface reactivity, we provide insights for designing heterojunction photocatalysts with tailored adsorption and redox functionalities.","PeriodicalId":427,"journal":{"name":"Separation and Purification Technology","volume":"5 1","pages":""},"PeriodicalIF":8.6,"publicationDate":"2025-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144176829","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}

Due to the significant economic value of both hydrogen and helium, the development of efficient recovery and separation technologies is critical. Currently, cryogenic distillation is the only commercially viable method for helium production, but it is highly energy intensive. While the emerging membrane technologies are capable of separating helium from nitrogen or methane, they are sometimes ineffective for the separation of hydrogen from helium due to similar molecular sizes. Hydrogen/helium separation is also challenging for pressure swing adsorption (PSA) technology as adsorbents with helium or hydrogen selectivity are scarce. In this study, we devised a novel PSA technology that employs the metal alloy LaNi₅ as an adsorbent to effectively separate hydrogen from helium, achieving an enriched helium purity of 99.82 % with a recovery rate of 95.78 % from a 5 % helium feed gas. Remarkably, the specific energy required for helium production from natural gas using the proposed PSA process is only about 2 % of that required by cryogenic distillation, making it particularly suitable for small to medium scale applications. Furthermore, we extended this method to a double-stage PSA system with LiLSX zeolite and metal alloy as adsorbents respectively, which shows great potential for hydrogen and helium recovery from natural gas. This innovative approach offers a more energy-efficient and cost-effective approach for the extraction and purification of these valuable resources.","PeriodicalId":427,"journal":{"name":"Separation and Purification Technology","volume":"93 1","pages":""},"PeriodicalIF":8.6,"publicationDate":"2025-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144177289","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 results indicated that under optimal pretreatment conditions (0.9 M C₂O₄²⁻ addition, 85 °C, 60 min), Cr(Ⅲ) and Al(Ⅲ) in the leaching solution were transformed from CrSO₄⁺ and Al(SO₄)₂⁻ to Cr(C₂O₄)₂⁻, Al(C₂O₄)₂⁻, and Al(C₂O₄)₃^3–.
