However, these approaches encounter significant drawbacks, including excessive waste generation, structural degradation, and limited efficacy for cationic contaminants. To overcome these challenges, this study proposes electrochemical activation as a sustainable method to enhance alum sludge adsorption performance by generating oxygen-containing functional groups (O-FGs) on its surface. In particular, cathodic activated AlS (E-AlS) leads to the formation of hydroxyl (–OH) and carboxyl (–COOH) groups, which served as key active sites for Pb(II) adsorption through complexation mechanisms. E-AlS effectively removed both Pb(II) and As within 4 h, showcasing its dual functionality for cationic and anionic contaminants. While HCl- and KOH-activated AlS also achieved 100 % Pb(II) removal, they caused substantial aluminum (Al) leaching, exceeding 1,000 mg/L, due to structural instability. In contrast, E-AlS minimized Al leaching, preserved structural integrity, and exhibited a 6.5-fold higher Pb(II) adsorption capacity than raw AlS. X-ray photoelectron spectroscopy (XPS) and machine learning (ML) validated the enhanced adsorption performance of E-AlS. These findings highlight electrochemical activation as a cost-effective and environmentally friendly remediation.</div></div>","PeriodicalId":258,"journal":{"name":"Bioresource Technology","volume":"430 ","pages":"Article 132563"},"PeriodicalIF":9.7,"publicationDate":"2025-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143860373","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

Hydrothermal liquefaction (HTL) has emerged as a promising approach for waste-to-energy conversion, effectively transforming lignocellulosic biomass into renewable biocrude.

This study focuses on enhancing the production and quality of low-phenolic biocrude via a sequential HTL process. The results revealed that sequential HTL achieved a high biocrude yield of 59.9%, with a concurrent reduction in phenolic content to 4.2%. This represents an 84.2% decrease in phenolic content compared to biocrude derived from direct HTL (280 ℃), achieving a tradeoff between biocrude yield and quality. Notably, GC–MS revealed that the biocrude produced through sequential HTL was enriched with fatty acids and esters accounting for 80.5%, contributing to the production of hydrocarbon fuels. Additionally, FT-ICR MS revealed that sequential HTL enhanced the biocrude quality and encouraged the production of light fuels. The petroleum fractionation analysis further revealed that sequential HTL-derived biocrude was more desirable in the downstream petroleum refining industry. The model compounds experiments revealed that phenols were likely to to be transferred to the oil phase at relatively high temperatures.
