Transport and retention of DOM at two comparatively low and high loadings on a homogenized subsoil sample were determined via column breakthrough experiments, where the role of water saturation and two consecutive wet-dry cycles were systematically compared. In the column effluent, dissolved organic carbon (DOC) and dissolved total nitrogen (TN) as well as aromaticity by the specific UV absorption at 280 nm (SUVA) were determined. The total retention of DOC following wet-dry cycles was significantly higher than under water saturated condition. Rewetting particularly led to stronger depletion of hydrophobic fractions in the leached DOM. This was especially evident when the DOM loading before drying was lower. Nevertheless, a consecutive second wet-dry cycle led to comparatively less depletion of hydrophobic fractions in the leachate in both DOM loadings. Significant decreases in soil wettability and surface free energy were also evident after DOM percolation, particularly after drying, as determined by analyzing the sessile drop contact angle. We conclude that wet-dry cycles increase DOM retention in soils. This is generally due to more DOM interactions with soil mineral surfaces amplifying the retention of hydrophobic fractions. Retention of less hydrophilic DOM in the second consecutive wet-dry cycle indicates the formation of layered coatings on mineral surfaces. These coatings can lead to soil water repellency and influence other soil properties.</div></div>","PeriodicalId":100290,"journal":{"name":"Colloids and Surfaces C: Environmental Aspects","volume":"3 ","pages":"Article 100086"},"PeriodicalIF":0.0,"publicationDate":"2025-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145518950","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Conventional methods are often labor-intensive, resource-demanding, and environmentally harmful. Three-dimensional (3D) scaffolds, akin to lattice girders in building construction, offer structural durability and can serve as highly efficient oil sorbent. The fabrication of 3D scaffolds is a preferred method for removing contaminants, particularly oil from oily wastewater, owing to their exceptional oil sorption capacity. Present research examined the development of a new, high-temperature-stable adsorbent material for oil spill remediation. Polyetherimide (PEI) based macroporous scaffolds were fabricated via high internal phase emulsion (HIPE) templating and freeze-drying to exploit their high oil sorption capacity and high temperature stability. The scaffolds were crosslinked with ethylenediamine (EDA) to increase their mechanical resiliency and utility for multiple use cycles. Characterization techniques such as optical microscopy, SEM, FTIR and gravimetric tests were carried out to evaluate the structure and efficacy of the scaffolds. Oil sorption capacity of scaffolds was assessed at room temperature and at 150°C, and a significant increase in sorption capacity was found at high temperature. Kinetic modeling using pseudo-first-order, pseudo-second-order, and intraparticle diffusion models revealed that physisorption is the dominant mechanism. Wettability of the scaffolds was investigated using capillary pressure measurements which demonstrated an easy oil adsorption into the porous framework. To complement the detailed performance metrics provided, this study also presents an in-depth discussion of the underlying mechanisms, emphasizing multi-stage oil adsorption involving bulk diffusion, film diffusion, and intraparticle transport. Capillary-driven wicking and the scaffold’s open-cell architecture facilitate rapid oil uptake. Current study has demonstrated the application of PEI-based HIPE scaffolds as a very efficient, low-cost, and eco-friendly approach for high-temperature oil spill remediation, which may further be used to several untapped applications.</div></div>","PeriodicalId":100290,"journal":{"name":"Colloids and Surfaces C: Environmental Aspects","volume":"3 ","pages":"Article 100077"},"PeriodicalIF":0.0,"publicationDate":"2025-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144758058","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address the challenge of managing these pollutants, the treatment processes of a full-scale electroplating wastewater treatment plant in Shenzhen, China, were investigated in this study. The physicochemical treatment units were examined regarding the removal efficiency of target pollutants, sludge production, and cost implications. Substantial variability in treatment performance was observed due to fluctuations in wastewater quality and quantity. The chemical oxidation demand (COD) removal by the physicochemical treatment ranged from 24.26 % to 78.6 %, with effluent concentrations between 400–1000 mg/L, affected by refractory substances and improper dosing. Heavy metal removal was more effective at higher influent concentrations, with chromium achieving up to 99.83 % removal, while nickel and copper showed inconsistent performance due to complexed forms and dosing issues. Nitrogen removal reduced the total nitrogen concentration from 75.43–351.09 mg/L to ∼25–100 mg/L, relying on oxidation (NaClO) and sedimentation, but left residual nitrogen for biochemical treatment. Phosphorus removal, primarily through chemical precipitation, reduced total phosphorous to < 10 mg/L in optimal cases but fluctuated significantly due to poor pH control and competing reactions. Overall, while primary sedimentation and chemical processes contributed significantly, challenges such as process instability, refractory pollutants, and improper dosing impacted treatment consistency. These findings underscore the importance of optimizing treatment parameters and adopting innovative strategies to enhance process stability and cost-effectiveness.
