Metal–organic framework (MOF) and covalent organic framework (COF) composites, with their multiple functional groups, are anticipated to show outstanding Pb (II) adsorption capabilities. Nevertheless, creating and developing COF and MOF composite adsorbents for highly efficient Pb (II) removal remains a challenge. In this study, we synthesized a core–shell ZnGlu@Bth-TFPOT-COF (referred to as M@C) adsorbent via Schiff base reaction. Adsorbent demonstrated remarkable properties, including excellent durability, specificity, and straightforward solid–liquid separation. Under 298 K and pH 6.0 conditions, M@C effectively adsorbed Pb (II) and achieved 49.40 mg/g adsorption capacity within 15 min. Remarkably, it effectively eliminated Pb (II) from a solution containing multiple ions, demonstrating an adsorption efficiency of 99.80% and a <i>K</i><sub><i>d</i></sub> (partition coefficient) of 4.99 × 10<sup>6</sup> mL/g in the presence of 10 other ions. The adsorption process was controlled by the Freundlich isotherm model, and the pseudo-second-order kinetic model validated that multilayer chemisorption was the mechanism for removing Pb (II). A thermodynamic study showed that the removal process was both spontaneous and exothermic. M@C exhibited outstanding adsorption performance, achieving a capacity of 476.19 mg/g, and demonstrated exceptional selectivity. This makes it an excellent material for the efficient and selective removal of Pb (II).</p>\u0000 </div>","PeriodicalId":8344,"journal":{"name":"Applied Organometallic Chemistry","volume":"39 4","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143689569","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, this study aimed to evaluate a composite of graphitic carbon nitride nanosheet (g-C<sub>3</sub>N<sub>4</sub>NS) and the biopolymer alginate for the removal of Congo red (CR) dye from aqueous media. To address the challenges associated with the independent use of calcium alginate and g-C<sub>3</sub>N<sub>4</sub>NS in water, particularly regarding recovery issues, silica-coated magnetic nanoparticles (SMNPs) were incorporated into the composite. To achieve this objective, an alginate-based bioadsorbent was synthesized by crosslinking sodium alginate with calcium chloride in the presence of g-C<sub>3</sub>N<sub>4</sub>NS and SMNPs using an in situ method. Structural characterization was conducted using BET, TGA, TEM, FE-SEM, and EDX-Mapping analyses. Subsequently, the bioadsorbent was utilized to remove CR dye. The influence of various parameters, including initial concentration, contact time, adsorbent dosage, and pH, was subsequently investigated. According to the isotherm models, the linear Langmuir model exhibited a good fit to the experimental data for CR, indicating a maximum adsorption capacity of 68.03 mg g<sup>−1</sup> at pH 5 within 120 min. The synthesized composite has the potential to pave the way for novel applications in both organic and inorganic transformations, as well as in the physical or chemical remediation of diverse pollutants.</p>\u0000 </div>","PeriodicalId":8344,"journal":{"name":"Applied Organometallic Chemistry","volume":"39 4","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143632865","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
