This study investigates the use of Metal–Organic Frameworks (MOFs), including both MIL-101(Cr) and its sulfonated derivative MIL-101-SO<small>₃</small>H, for efficient removal of barium ions in contaminated water sources. Sulfonation of MIL-101 at the metal center was shown to considerably increase its adsorption capacity compared to unmodified MIL-101 for barium ions, achieving 141.9 mg g<small>⁻¹</small> for Ba<small>²⁺</small> as compared to 54 mg g<small>⁻¹</small> for MIL-101. The study deeply looked into the effects of the pH, adsorbent dosage, initial Ba<small>²⁺</small> concentration, and contact time on adsorption efficiency. Approximately pH = 4 has been determined as the best for Ba<small>²⁺</small> adsorption at which the sulfonated MOF gave essentially complete removal efficiencies of 99% of the barium cations. The adsorption correlated with the Langmuir model indicates a homogeneous monolayer adsorption on the surface. MIL-101-SO<small>₃</small>H, given the superior characteristics of its adsorptive ability compared with other materials including MIL-101, is tested with ion coexistence and retention trials.

The novelty of this work lies in the development and application of BDOBH as a highly efficient, low-loading organic nucleator tailored to improve PLLA's crystallization behavior and thermal properties—key limitations in its broader industrial use. The evaluation is conducted through differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), Fourier-transform infrared spectroscopy (FTIR), and polarized optical microscopy. FTIR analysis reveals the presence of H-bonding interaction between BDOBH and PLLA. DSC results significantly improve PLLA's crystallization rate, with BDOBH in a concentration range from 0.3 to 0.7 wt%. The total crystallinity of PLLA increases from 12% to 56–60% without a change in PLA's crystallography; moreover, the maximum temperature of the cold crystallization peak shifts to a lower value by 35 °C after incorporating BDOBH-0.7 into PLLA. POM results reveal a drastic decrease in the spherulitic size of PLLA. Furthermore, the presence of BDOBH enhances the thermal stability of PLLA. The nonisothermal cold crystallization behavior of PLLA nucleated by BDOBH is evaluated using the modified Avrami and Mo models. Multiple indicators of nonisothermal crystallization, including the crystallization half-time and crystallization rate constant, indicate that BDOBH greatly expedites the crystallization process. The activation energy values of the plain PLLA and PLLA-BDOBH, as computed using the Kissinger–Akahira–Sunose (KAS) model, decrease when BDOBH is incorporated. These findings highlight BDOBH's potential as a cost-effective and scalable additive to tailor PLLA crystallization, supporting its use in environmentally friendly packaging, biomedical devices, and other high-performance biodegradable applications.</p>","PeriodicalId":102,"journal":{"name":"RSC Advances","volume":" 17","pages":" 13539-13551"},"PeriodicalIF":3.9,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2025/ra/d5ra00368g?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143879539","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
