While the MRTL model accounts for activity coefficients and the maximum adsorption capacity, the MRTL-area model further refines the physical representation by dividing the adsorbent surface into areas occupied by each molecule.

Both free radical pathway (•OH) and non-free radical pathway (1O2 and electron transfer) were involved in BPA degradation in BC/PS/ilmenite and BC/PS/hematite systems. Meanwhile, for both systems with higher Fe content (4%), the electron transfer pathway contributed more in BPA oxidation, in which electrons transferred from BPA to Fe/BC-PS* complexes. The existence of organic matter, including biochar, could facilitate PS activation by Fe-OM formation and promote Fe(III)/Fe(II) cycle.

Such hybrid composites provide a promising approach for the simultaneous removal of dyes and heavy metal ions from wastewater. This study focused on the integration of aminated chitosan (AmCs with ZIF-8, followed by surface modification with cetyle triethyl ammonium bromide (CTAB), resulting in the development of a novel ZIF-8@AmCs/CTAB composite for the removal of Crystal violet (CV) dye and Cr(VI) metal ions from water.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> RESULTS</h3>\u0000 \u0000 <p>Spectroscopic techniques and density functional theory (DFT) were used to characterise the composite. Its high surface area (1350 m²/g), hierarchical porosity, and a positively charged surface enable results of maximal uptakes of 782 mgg-¹ for CV dye, and 286 mgg⁻¹ for Cr(VI) ions. Using non-covalent interactions (NCI), hydrogen bonding, and electrostatic interactions from AmCs/CTAB, microporous confinement by ZIF-8, synergistic interactions achieved removal efficiencies of over 98% for CV and over 70% for Cr(VI).</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> CONCLUSION</h3>\u0000 \u0000 <p>Our work demonstrates that ZIF-8@AmCs/CTAB is a promising, cost-effective composite for treating multi-pollutant wastewater. The composite shows efficient and stable performance even after five cycles of use and maintains a removal efficiency of more than 92%. and durability over a broad pH range (2–10). © 2026 Society of Chemical Industry (SCI).</p>\u0000 </section>\u0000 </div>","PeriodicalId":15335,"journal":{"name":"Journal of chemical technology and biotechnology","volume":"101 9","pages":"1877-1890"},"PeriodicalIF":2.7,"publicationDate":"2026-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148662644","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
