Therefore, achieving the simultaneous removal of phosphates and organic matter from water bodies is significant. This study reports an excellent Fe₃Ce₁Oₓ(CA) functional material synthesized via a simple one-step co-precipitation method for hydroquinone (HQ) degradation through a Fenton-like reaction while simultaneously adsorbing phosphate. Experimental results show that the Fe₃Ce₁Oₓ(CA) materials exhibit a 92 % HQ degradation efficiency and an 80 % phosphate adsorption efficiency. Systematic characterization confirms that the Fe–Ce synergistic effect enhances the Fe(II) content, significantly promoting H₂O₂ activation. Electron paramagnetic resonance and radical scavenger experiments reveal that ¹O₂, O₂^•⁻, and •OH play essential roles in organic degradation, with •OH being the dominant reactive species. Introducing citric acid increases the Ce(III) content in the Fe–Ce bimetallic oxide composite, enhancing its phosphate adsorption performance. This material successfully achieves both HQ degradation and phosphate removal, and these findings suggest that the Fe₃Ce₁Oₓ(CA)/H₂O₂ system can potentially treat wastewater with combined organic and phosphate pollution. This approach, which achieves multifunctionality in water treatment by regulating the composition of environmental functional materials, enhances the practical application potential of such materials.</div></div>","PeriodicalId":20743,"journal":{"name":"Process Safety and Environmental Protection","volume":"199 ","pages":"Article 107322"},"PeriodicalIF":6.9,"publicationDate":"2025-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144070643","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Conventional scanning path planning typically relies on experience-based placement of scan points, lacking theoretical support and struggling to adapt to complex station structures and dynamic risk changes. The process begins with the creation of a 3D model, which captures the spatial details of the equipment and its environment, providing the foundation for subsequent risk assessment. Dynamic Bayesian Networks (DBN) integrate historical data, real-time monitoring information, and expert insights to assess equipment status and identify high-risk zones. Computational Fluid Dynamics (CFD) simulations then model gas dispersion within these zones, generating detailed gas cloud distributions from which critical scanning points are extracted. Finally, a non-cooperative game-theoretic framework combined with Genetic Algorithms (GA) optimizes the laser platform’s scanning trajectory based on the extracted scanning points and identified high-risk areas. The proposed method demonstrates a 37.8 % reduction in scanning path length, a 22 % improvement in detection accuracy, and significant reductions in energy consumption and detection time.

A multi-source weighted mean discrepancy alignment strategy is proposed for fine-scale distribution discrepancy reduction among multiple modes. A coefficient matrix imposed low-rank constraint is learned so that the proposed FTPLG captures shared information across different modes.

However, inadequate recycling of this slag may lead to significant environmental degradation and pose serious risks to human health. In this study, an innovative suspended magnetization roasting-magnetic separation (SR-MS) process is proposed for the efficient recovery of iron from sulfuric acid slag. The iron phase transformation behavior of the slag in the reduction/magnetization process was systematically investigated through thermodynamic analysis. Key process parameters were optimized to achieve enhanced iron recovery efficiency, yielding optimal experimental conditions and high-quality iron-rich products. When the calcination temperature was 525 °C, the reducing agent concentration was 30 % (CO:H₂=1:3), the roasting time was 20 min, and the magnetic separator field intensity was 1200 Oe, the concentrate iron grade was 63.24 % and the iron recovery rate was 92.20 %. Under a calcination condition of 525 °C, with reducing agent dosage maintained at 30 % (CO:H₂=1:3) and roasting duration fixed at 20 min, magnetic separation conducted under 1200 Oe field strength yielded concentrate with 63.24 % Fe content alongside 92.20 % metal recovery. The mechanism was studied by chemical multi-element analysis, phase analysis, VSM analysis and SEM analysis of the slag samples in each stage of the suspension magnetization roasting-magnetic separation (SR-MS) process. It was found that through suspension magnetization roasting (SMR) pretreatment, hematite almost transformed into magnetite with greater magnetism, and microscopic morphology observation revealed significant changes on its mineral surface. The Suspension Magnetization Roasting (SMR) technique not only modifies the physicochemical surface properties of materials, but more significantly induces microstructural reorganization through crack propagation and pore evolution mechanisms. This structural transformation substantially enhances pore distribution characteristics, manifesting as measurable expansion in specific surface area and stepwise increase in total pore volume. The demonstrated that the raw slag is transformed into magnetite. The phase transition from hematite to magnetite during roasting was confirmed through FT-IR spectroscopic analysis. These findings provide critical insights for advancing research and development in sustainable iron resource recycling and innovative solid waste disposal technologies.</div></div>","PeriodicalId":20743,"journal":{"name":"Process Safety and Environmental Protection","volume":"199 ","pages":"Article 107321"},"PeriodicalIF":6.9,"publicationDate":"2025-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144070645","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A case study of a tank farm is applied to illustrate the applicability of the proposed methodology, in which different design schemes of barrier systems for increasing resilience are discussed and some recommendations are given.

This study subjected consecutively recovery (supercritical CO₂: SC-CO₂) and treatment (supercritical water oxidation: SCWO) by using the supercritical fluid method. In this study, sour cherry UF retentate with high-load organics, which include especially valuable phenolics was used. The mean COD and total phenolic substance content (TPC) were determined as 15,650 mg/L and 457 mg GAE/L, respectively. Recovery efficiencies of TPC and total flavonoid substance content (TFC) of extracts were up to 5 % and 10 % with SC-CO₂ extraction, respectively. Additionally, the highest enrichment efficiencies were determined as 35 % and 140 %. While the TPC of sour cherry UF retentate was 72 mg/100 g sample, it increased up to 278 mg/100 g in the extract obtained under 40 °C and 30 MPa. Flavonoids from phenolic substances had high recoverability in SC-CO₂ compared to the other phenolic groups. Following extraction, the samples were treated using the supercritical water oxidation process. Wastewater with high organic load was effectively treated in a short time (15 min) and the removal efficiencies changed between 78 % and 98 %. Additionally, toxicity tests were conducted in selected optimum extraction (27 MPa and 40 °C) and oxidation (1.68 DOD and 3 min) conditions, and the toxicity units of extracted and treated wastewaters decreased compared to those obtained from raw wastewater for <em>Daphnia magna</em> and <em>Vibrio fischeri</em> toxicity tests.

The findings show that open doors result in higher sound levels than closed doors, and corridor-based alarms typically fail to meet the recommended 75 dBA threshold needed to awaken sleeping occupants.
