Subsequently, the covalent triazine frameworks (CTFs) were formed in situ on the carbon nanofiber to prepare the novel Fe-doped carbon/covalent triazine frameworks (C/Fe@CTFs). The C/Fe@CTFs membrane exhibits selective adsorption on malachite green (MG) due to the confining effect of the CTFs. The adsorption experiments reveal that pseudo-second-order kinetics and Langmuir isotherm model fit better to the real process on MG adsorption, and DFT calculation is utilized to investigate the affinity between absorbent and adsorbate by determining the electron density and molecular orbital of each sample. Moreover, the C/Fe@CTFs presents improved photocatalytic effect against MG with a removal rate of 93.6 % with promoted service life under simulated sunlight irradiation. In brief, the C/Fe@CTFs membrane displays selectively adsorbing, efficiently photo-catalysing, improved bacteria inhibiting is a promising candidate for practical application on dye pollutant removal in water treatment.</div></div>","PeriodicalId":100480,"journal":{"name":"Environmental Chemistry and Ecotoxicology","volume":"7 ","pages":"Pages 1178-1188"},"PeriodicalIF":9.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144221593","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}

By integrating a traditional geochemical model and multivariate statistical analysis into a positive matrix factorization (PMF) method, we quantitatively identified the possible sources of HM contamination in the sediments. The total concentrations of sediment HMs distinctly exceeded local background values and were higher in the DSR compared to the XZR. The enrichment levels of HMs were influenced not only by sediment properties, such as texture, but also, more critically, by the distribution of contamination sources. Sediment Cu, Zn, Cd, and Ni were dominated by acid-soluble fractions (31.4–56.2 %), exhibiting a great mobility potential; while reducible and oxidizable fractions were the predominant geochemical forms for Pb (45.0 ± 12.8 %) and Cr (37.3 ± 7.09 %).

Trace element concentrations in the edible portions (flesh) of 10 cultivated fish species (30 samples) were determined using an Atomic Absorption Spectrophotometer (AAS).

Herein, we synthesized a molecularly imprinted MOF/PVDF electrospinning nanofibrous membrane, which is designed for selective adsorption of bisphenol A (BPA), photocatalytic degradation of methylene blue (MB), and efficient inhibition against bacteria in treating wastewater. Firstly, the as-prepared MOF/PVDF molecularly imprinted polymer membrane (MOF/PVDF-MIM) exhibits a higher affinity for BPA compared to other model pollutants attributing to the molecular imprinting effect. The adsorption mechanism was also investigated, indicating that the pseudo-second-order kinetics and Langmuir isotherm model closely match the adsorption process of the MOF/PVDF-MIM on BPA. In addition, the MOF/PVDF-MIM demonstrates excellent photocatalytic performance towards MB, achieving a degradation rate of up to 95.2 % under simulated sunlight irradiation. Moreover, the as-prepared membrane shows enhanced structural stability after several rounds of adsorption-desorption or degradation cycle, with a high adsorption rate of 53.1 % for BPA and a photocatalytic efficiency of 66.6 % for dye pollutants.
