In this work, magnetic beads were separated from industrial waste fly ash by wet magnetic separation and used as magnetic seeds (MS-CFA) in magnetic coagulation (MC). The superiority of MC was evaluated by comparison with traditional coagulation (TC). Meanwhile, The potential and feasibility of MS-CFA were evaluated by also employing Fe 3 O 4 in the MC process. MS-CFA was characterized by SEM, XRD, VSM, and XPS. The results showed that MS-CFA was a composite microsphere crystal with a saturation magnetization of 33.71 emu/g. The addition of MS-CFA reduced the residual turbidity from 10.87 NTU to 3.27 NTU and increased the chemical oxygen demand (COD) removal rate from 42.92% to 64.24%. MS-CFA achieved water treatment performance comparable to or even better than Fe3O4, especially in organic matter removal. As a waste-derived material, MS-CFA not only reduces costs but also provides stronger adsorption for organic pollutants. This study provides a reference route for developing low-cost and high-efficiency magnetic coagulation technology.","PeriodicalId":11445,"journal":{"name":"E3S Web of Conferences","volume":"728 1","pages":"01008-01008"},"PeriodicalIF":0.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.e3s-conferences.org/articles/e3sconf/pdf/2026/46/e3sconf_eeupd26_01008.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148672199","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 experimental study investigated the removal of a pharmaceutical substance, roxithromycin, using carbonation temperature and current intensity as the independent variables. The research findings demonstrated that carbon aerogel electrodes, subjected to different carbonization temperatures, possess a distinctive three-dimensional mesh architecture. Furthermore, it was observed that both the degree of graphitization and the presence of unsaturated carbon structures within the material intensified as the carbonization temperature was elevated. Under optimal experimental conditions (10 mA/cm2 electrical density and 600℃ carbonisation temperature), the removal rate of roxithromycin reached 75.06%.

However, the separation of HPA catalysts after biodiesel production is challenging due to their homogeneous catalytic nature. This study aims to develop magnetic vanadium-substituted HPAbased ZIF-8 composites to create a catalyst for biodiesel production from WCO that is more efficient and easier to separate. In this work, a range of analytical methods was utilized to characterize the catalyst, such as Fouriertransform infrared spectroscopy (FTIR), scanning electron microscopy coupled with energy dispersive X-ray spectroscopy (SEM-EDX), highresolution transmission electron microscopy (HRTEM), and a vibrating sample magnetometer (VSM). The successful incorporation of HPA acid into the magnetite ZIF-8 nanocomposite was indicated by prominent bands in the FTIR analysis, and this formation was further validated by EDX analysis. The VSM results also revealed that the nanocomposite has good magnetic responsiveness, facilitating catalyst separation and recycling. The magnetic ZIF-8 composites functionalized with H 6 PV 3 MoW 8 O 40 demonstrated significant potential for sustainable biodiesel production from WCO.","PeriodicalId":11445,"journal":{"name":"E3S Web of Conferences","volume":"603 1","pages":"03006-03006"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.e3s-conferences.org/articles/e3sconf/pdf/2025/03/e3sconf_isgst2024_03006.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147334027","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}

This study explores glycerol pitch, a biodiesel by-product, as a sustainable precursor for synthesizing polymerized adsorbents. Sodium hydroxide (NaOH), potassium hydroxide (KOH), and lithium hydroxide (LiOH) were evaluated as catalysts for glycerol polymerization, with NaOH-based adsorbents demonstrating the highest amoxicillin removal efficiency. To identify the key factors influencing adsorption performance, a two-factorial experimental design was employed, investigating polymerization temperature, polymerization time, alkali concentration, activation temperature, and activation time. A total of 32 experimental runs confirmed calcination temperature and time as the most significant parameters affecting amoxicillin removal, achieving efficiencies of up to 14.43%. These findings validate the critical parameters for adsorbent preparation, forming the basis for subsequent optimization using response surface methodology (RSM). The study underscores the potential of NaOH-catalyzed glycerol-derived adsorbents as cost-effective and sustainable solutions for pharmaceutical wastewater treatment, contributing to waste valorization and environmental sustainability.","PeriodicalId":11445,"journal":{"name":"E3S Web of Conferences","volume":"635 1","pages":"02001-02001"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147334077","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}

However, there are some problems in this method, such as large differences among different decomposed composts, unstable compost between batches, subjective factors interfering greatly with the experimental results, and the nutrient composition of compost culture solution in vermiculite scheme is not clearly defined. In this paper, the effects of compost and vermiculite inoculants were compared by experiments. In addition, the formula of vermiculite culture solution was optimized, and the experimental results showed that the determination efficiency of product degradation rate could be effectively improved by adding specific microbial bacteria (potassium bacteria, bacillus group, lactic acid bacteria group, etc.). At the same time, the optimized culture solution formula can better control the nutrient composition, solve the problems of batch to batch instability, artificial factors, and improve the reproducibility and repeatability of detection. This is of great significance for promoting the application and development of biodegradable plastics testing standards. Through these improvements, the performance of biodegradable plastics can be more effectively assessed, the rational use of environmentally friendly materials and the control of plastic pollution can be promoted, the application of degradable materials in packaging materials, agriculture, medical care, textile and clothing, new energy and other fields can be promoted, the green transformation of the industry can also help “carbon peak” and “carbon neutral” realization.","PeriodicalId":11445,"journal":{"name":"E3S Web of Conferences","volume":"615 1","pages":"02005-02005"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.e3s-conferences.org/articles/e3sconf/pdf/2025/15/e3sconf_eppc2025_02005.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147877313","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}

Currently, bulk CPCMs are primarily prepared using the mixed sintering method, but their application is limited by issues such as easy collapse, leakage, and the fact that they can only be stacked for use. To address these issues, this study proposes a novel method that combines extrusion-spheronization with mixed sintering to produce composite phase change particles with high fluidity, excellent leakage resistance, and high energy storage density. An MgO skeleton is incorporated into the NaCl-KCl phase change material to provide structural support, prevent leakage and deformation, and enhance the thermal conductivity.
