Diatomite is a good absorbent and a friendly and efficient material for removing pollutants from organic matter. In this study, diatomite from Phu Yen, Vietnam, was treated with many different agents, i.e., HCl, H₂SO₄, and NaOH, resulting in good adsorption of various antibiotics, such as tetracycline (TC), ciprofloxacin (CIP), tylosin (TLS), trimethoprim (TMP), and florfenicol (FFC). Furthermore, the TC antibiotic was chosen as a pollutant model to study the adsorption environment, adsorption isotherms, adsorption kinetics, and adsorption thermodynamics. Compared with raw diatomite, diatomite treated with HCl (D-HCl) has superior TC adsorption performance due to the removal of lotus fruit receptacle bud-like particles in the structure, which helps clear the pores and increases the specific surface area. Moreover, the change in surface charge leads to an increase in the electrostatic interaction force with TC. The TC adsorption of D-HCl follows the second-order kinetic model and the Langmuir isotherm model, with a high correlation coefficient of 0.9965 and a maximum adsorption capacity of 90.09 m² g⁻¹ at room temperature. The intra-particle diffusion model with the largest initial rate constant (k_int1) suggests that the TC rapidly occupied the surface active sites of the D-HCl adsorbent. The high secondary rate constant (k_int2) indicates that intragranular diffusion then proceeded immediately, which is consistent with the presence of multiple pore sizes within the D-HCl material. The adsorption thermodynamic parameters also show that the adsorption process occurs naturally, and the bond between TC and the D-HCl surface is a physical bond, indicating that D-HCl has potential for practical applications in removing antibiotics from water sources. Additionally, D-HCl shows promise as a perfect carrier in the field of photocatalysis.</p></div>","PeriodicalId":660,"journal":{"name":"Journal of Porous Materials","volume":"32 1","pages":"155 - 168"},"PeriodicalIF":2.5,"publicationDate":"2024-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143109549","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, it has a non-spherical particle shape, making it difficult to use in solid dosage forms, where spherical particles are preferred for better flow and distribution. In this regard, this study presented a novel strategy to produce spheric SBA-15 using polymeric macrospheres of a pharmaceutical grade acidic-resistant copolymer (Eudragit^®S) stabilized with Pluronic^® 123, as a template. The macrospheres of Eudragit^®S were fabricated using the double emulsion (W1/O/W2) solvent-diffusion technique and then were used as a template to synthesize macrospheres of SBA-15 following acidic hydrolysis. The physicochemical analysis revealed that the SBA-15 has a spherical morphology (SEM) with pores arranged in a hexagonal lattice (TEM). The XRD showed signals at 0.71, 0.88 y 2.03 °2θ, that were indexed at the Miller indices (100), (110), (200). Nitrogen adsorption-desorption isotherms (type IV, H3) demonstrated mesoporous characteristics with a pore size of 9.3 nm, a wall thickness of 3 nm, a pore volume of 0.7538 cm³g⁻¹, and a surface area of 640 m²g⁻¹. These SBA-15 macrospheres also showed a zero-order release of ibuprofen. The SBA-15 formation using Eudragit^®S macrospheres suggests that P123 on the macrosphere acts as a spherical core, as shown by FT-IR analysis. The acid-resistant copolymer maintained macrosphere integrity, enabling the assembly of the SBA-15 mesostructure in a 24-hour manufacturing time under acidic conditions.</p></div>","PeriodicalId":660,"journal":{"name":"Journal of Porous Materials","volume":"32 1","pages":"141 - 153"},"PeriodicalIF":2.5,"publicationDate":"2024-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10934-024-01685-7.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143109755","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
