As a typical organic phosphorus pollutant, THPS poses potential threats to both the ecological environment and human health. Herein, this investigation used the microscale zero-valent iron (mZVI)/O₃ process to eliminate THPS from aquatic environments. The mZVI/O₃ system demonstrated superior removal performance, achieving high removal efficiencies of total phosphorus (TP), organic phosphorus (OP), and chemical oxygen demand (COD) compared to traditional systems (i.e., mZVI alone, O₃ alone, Fe²⁺/O₃, and Fe³⁺/O₃). Moreover, batch experiments were conducted to optimize the key operational parameters (such as initial pH, mZVI dosage, O₃ concentration, and stirring rate). The TP, OP, and COD removal efficiencies in the mZVI/O₃ system reached 97.10%, 97.31%, and 81.56% within 20 min, respectively, under optimized conditions. Based on the experimental results and characterization analysis, the THPS degradation mechanism by the mZVI/O₃ system was primarily a combination of oxidation (60.37% ± 7.41%) and flocculation (39.63% ± 7.41%). Furthermore, the mZVI/O₃ system demonstrated unprecedented removal performance in various actual wastewater samples. The system eliminated organic pollutants and improved biodegradability of actual wastewater. This study not only establishes the mZVI/O₃ process as a robust, cost-effective, and environmentally sound approach for OP degradation but also offers substantial promise for practical wastewater treatment applications.</p><h3>Graphical abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":640,"journal":{"name":"Journal of Leather Science and Engineering","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://JLSE.SpringerOpen.com/counter/pdf/10.1186/s42825-025-00195-9","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143919131","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}

Herein, a liquid sulfonate chain extender, 2,3-dihydroxypropanesulfonic acid triethylamine salt (DHPSTEA), was initially synthesized. A series of poly(carbamoyl sulfonate) tanning agents (CTAS) were then synthesized using DHPSTEA and various diisocyanates as reaction monomers, with sodium bisulfite serving as the blocking agent and without utilizing organic solvents. CTAS demonstrated a blocking ratio of &gt; 99% and satisfactory stability under acidic conditions at room temperature. Application experiments revealed that CTAS exhibited excellent tanning performance, with the parent diisocyanate monomer markedly influencing their tanning properties. CTAS synthesized with dicyclohexylmethane-4,4′-diisocyanate resulted in optimal product performance, yielding a shrinkage temperature of 83.2 °C at a 6% dosage. CTAS-tanned leather displayed excellent collagen fiber dispersion, yellowing resistance and mechanical properties. Additionally, CTAS is easy to biodegrade (BOD₅/COD &gt; 0.45).

This investigation introduces a novel approach for analyzing fatliquor migration by measuring its spreading area on collagen fiber membranes. By applying 300 mg of fatliquor onto 0.5 mm square membranes (10 cm × 10 cm), distinct oil spots were observed, enabling analysis of migration behavior. Using stearic acid as a standard reference compound effectively minimized the influence of different leather sections on fatliquor migration. Fatliquors with low molecular weight, low melting point and high aliphatic ester content exhibited obvious migration potential. Organic-tanned leathers and sulfated fatliquors displayed weak interactions, resulting in easy fatliquor migration within the leather. Conversely, metal-tanned leathers and phosphorylated fatliquors demonstrated strong interactions, effectively hindering migration.

The experimental results revealed that the tear strength of leather was affected by the crosslinking agents, which could be further adjusted by the filler. Accordingly, a simple method using mercury intrusion porosimetry has been proposed for determining the FB size based on the crack-bridging model.

The I-1 peptide was shown to increase the survival rate of haematopoietic stem cells following injury induced by 5-fluorouracil (5-FU), increasing the survival rate from 65.40 to 105.28%, thereby exhibiting significant haematopoietic activity. More importantly, the mechanism underlying the haematopoietic activity of the I-1 peptide was analogous to activate the JAK/STAT signalling pathway mediated by granulocyte‒macrophage colony‒stimulating factor.
