Summary: In this study, a magnetic NH2-MIL-101(Al)/chitosan nanocomposite (MIL/Cs@Fe3O4 NCs) was synthesized and successfully used for the removal of azithromycin (AZT) from aqueous solutions. The synthesized nanocomposite was characterized using various techniques, and the optimization of key factors in the AZT adsorption process was carried out using response surface methodology. The results showed that the optimized conditions led to high removal efficiency and adsorption capacity of AZT. The thermodynamic and kinetic analysis indicated that the adsorption process was spontaneous and endothermic in nature. The reuse of the nanocomposite and its performance under real conditions were also evaluated.

Summary: This study reports on the adsorption of tetracycline using magnetic chitosan as the adsorbent. The highest adsorption capacity was achieved at pH 7.0, and the efficiency of the adsorbent depended on pH, initial concentration, and dosage. Ionic strength significantly affected the process. The Sips and Elovich models provided the best fit for the experimental data, indicating heterogeneous surface adsorption predominantly through chemical mechanisms. The adsorption of tetracycline was governed by hydrogen bonds and cation-pi interactions, and the incorporation of magnetite on the chitosan surface enhanced its removal efficiency. Thermodynamic parameters suggested a spontaneous and exothermic process. Magnetic chitosan proved to be effective in tetracycline removal even after multiple adsorption/desorption cycles.

Summary: Polypyrrole-gelatin aerogels containing magnetic barium ferrite particles were synthesized and used for the removal of Cr(VI) from aqueous media. The optimal pH for adsorption was found to be 4, due to the dominance of HCrO4- species and its better adsorption and reduction compared to CrO42-. The presence of magnetic particles did not affect the adsorption performance of the aerogels. The adsorption mechanism involved electrostatic interaction between chromium and the adsorbent.

Summary: In this study, amino-functionalized monodisperse polymeric microcapsules were prepared using a microfluidic approach for efficient adsorption of heavy metal ions from aqueous solution. The presence of abundant amine groups on the shell of the microcapsules played a key role in the successful adsorption of Cu2+, Cd2+, and Zn2+ ions. The cyclic adsorption-desorption efficiency of the amino-functionalized microcapsules remained stable for five cycles, demonstrating their potential for practical applications in heavy metal ion removal.

Summary: In this study, magnetic chitosan cross-linked gelatin polymer composites (MCGC) were successfully prepared and showed excellent adsorption performance and easy separation. The adsorption kinetics followed the pseudo-second order model, and the adsorption isotherms fitted best with the Redlich-Peterson equation. The thermodynamic studies suggested that the adsorption process was exothermic and spontaneous. The adsorption mechanism involved electrostatic interaction, hydrogen-bond interaction, and 7C-7C stacking between the dyes and MCGC. Desorption and regeneration experiments confirmed the MCGC's high regeneration properties and reusability as an adsorbent.

Summary: The novelty of this work lies in the modified single walled carbon nanotube with magnetic CoFe2O4 nanoparticles and p-cyclodextrin/folic acid as a targeted delivery carrier for controlled release of anticancer active agent (chlorogenic acid). The effective factors, including pH, contact time, and nanoadsorbent dosage, were optimized using response surface methodology and central composite design. The results showed that a quadratic model was suitable for fitting the experimental data, and a maximum adsorption efficiency of 87.25% was predicted under specific conditions. The nanoadsorbent was thoroughly characterized using various techniques. The adsorption isotherm and kinetic results were well described by the Langmuir and pseudo-second-order models, respectively. The release of chlorogenic acid showed sustained release, and the release rate was influenced by pH. The cytotoxicity test confirmed the biocompatibility of the single walled carbon nanotube and nanocarrier.

Summary: pH-sensitive magnetic nanocarrier was developed for doxorubicin delivery by grafting hyaluronic acid/beta-cyclodextrin onto Fe3O4 magnetic nanoparticles. The nanocarrier demonstrated strong pH-dependent release behavior, with higher drug release at pH 5.6 compared to pH 7.4. The release mechanism was determined to be controlled by Fickian diffusion kinetic. The surface modification of the magnetic nanoparticles greatly influenced drug sorption and was more compatible with Langmuir isotherm and pseudo-second-order kinetic models. Thermodynamic parameters indicated that the doxorubicin adsorption was endothermic and spontaneous, suggesting physiochemical sorption. These findings highlight the potential of pH-sensitive nanocarriers for drug delivery.

Summary: Millions of people are exposed to highly toxic ions, such as arsenic, cadmium, and lead, which have detrimental effects on human health and the environment. A new bio-nanocomposite material, composed of magnetic MnFe2O4 nanoparticles and functionalized mesoporous silica (SBA-15) with adenine, has been developed for the efficient removal of toxic ions from water. The material exhibited high removal efficiency for arsenic, cadmium, and lead ions, with maximum adsorption capacities of 21.99 mg g-1, 29.62 mg g-1, and 31.01 mg g-1, respectively. The bio-nanocomposite also showed good recyclability and demonstrated effectiveness in real water samples. Overall, this study highlights the promising potential of the MnFe2O4@SBA-15@(CH2)3-Ade material for heavy metal removal.
