SEM reveals that the terephthalaldehyde-based polymer has a higher number of micro-rods than that of the isophthalaldehyde-based polymer, while the number of microspheres is lower, as well as BET indicates that the surface area of the terephthalaldehyde-based polymer is more than twice that of the isophthalaldehyde-based polymer. Methylene blue (MB), rhodamine B (Rh-B) and brilliant blue FCF (BBF) were used as pollutants, and the effects of adsorption dosage, temperature and time on the adsorption properties of polymer particles were studied, respectively. The adsorption experiments show that the max adsorption efficiency of MB, Rh-B and BBF are 81.5% (MB), 97.8% (Rh-B), and 69.0% (BBF) for the terephthalaldehyde-based polymer, as well as the max adsorption efficiency of MB, Rh-B, and BBF are 28.1% (MB), 74.2% (Rh-B) and 76.9% (BBF) for the isophthalaldehyde-based polymer, respectively. The adsorption kinetic analysis demonstrated that the adsorption of MB and Rh-B onto the terephthalaldehyde-based polymer and BBF onto the isophthalaldehyde-based polymer follows the pseudo-first-order kinetic model, while the adsorption of BBF onto the terephthalaldehyde-based polymer and MB and Rh-B onto the isophthalaldehyde-based polymer conforms to the pseudo-second-order kinetic model. In addition, the relevant parameter <i>R</i><sup>2</sup> of adsorption model shows that the adsorption of dyes onto the terephthalaldehyde-based and isophthalaldehyde-based polymers conforms to the Freundlich adsorption isothermal model. These indicate that the terephthalaldehyde-based polymer, which is mainly dominated by rod-shape structures, has a better ability to adsorb MB, Rh-B, and BBF than that of the isophthalaldehyde-based polymer.</p>","PeriodicalId":761,"journal":{"name":"Russian Journal of General Chemistry","volume":"96 11","pages":""},"PeriodicalIF":1.0,"publicationDate":"2026-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149338130","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
