“…This extraordinary union is believed to stem from the surface charge and chemical groups on Ag‐MOF‐NH 2 , as they yield an abundance of accessible sites for AMX molecules to latch on to. Consequently, the adhesion of AMX to Ag‐MOF‐NH 2 is exceptionally strong 16 . To understand how electrostatic forces affect the adsorption on Ag‐MOF‐NH 2 , we must consider both its surface charge and the dissociation constant (pKa) of AMX.…”

Exploring the potential of silver metal organic frameworks (Ag-MOF), we modified it with sulfanilamide (Ag-MOF-NH 2 ) to create an efficient means for the adsorption of amoxicillin (AMX) from aqueous solutions. We characterized this new material with various imaging and analyzation techniques. Investigations into adsorption were conducted with varying solution pH, contact time, and adsorbent dosages. Moreover, the kinetics and adsorption isotherms were also tested by different models. Results revealed that equilibrium was reached between the antibiotic and the adsorbents within 100 min, with 1.93 and 2.63 mmolÁg À1 as the maximum adsorption capacities of Ag-MOF and Ag-MOF-NH 2 , respectively. The adsorption of AMX onto the adsorbents is closely in line with the pseudo-second-order kinetic model, intraparticle-diffusion model, and Langmuir isotherm, suggesting that the surface of the adsorbent is homogeneous and that the highest binding sites are filled first. By utilizing this data, an engaging conclusion can be drawn: the process of adsorption is efficient and effective. Optimizing adsorption results with Box-Behnken design (BBD) and Response Surface Methodology (RSM) produced impressive outcomes. Additionally, experiments were conducted on non-buffered AMX solutions at various NaNO 3 concentrations to ascertain the influence of the electrolytes' composition. Surprisingly, its capacity to take up the element was affected by different concentrations and has ability to be reused several times by capacity above 80% for up to four cycles. Discovering the intricate mechanisms behind AMX adsorption, such as electrostatic forces, π-π interactions, H-bonding, and pore filling, proves to be an invaluable asset in reducing its concentration from real water samples. The mighty potential of Ag-MOF and Ag-MOF-NH 2 makes them excellent adsorbents with removal efficiencies ranging between 86% and 97% making them ideal for industrial uses and protecting our environment.

During the synthesis of polyvinyl butyral (PVB), sodium dodecyl sulfonate (SDS) is generally added in appropriate amounts, which prevents PVB from agglomeration but also causes PVB to turn yellow. The removal of SDS and its final residue in PVB are closely related to the adsorption performance of SDS on PVB. In this study, PVB with a high acetal degree (81.96 mol %) was synthesized by polyvinyl alcohol and butyraldehyde and was characterized by 1H NMR, Fourier transform infrared spectroscopy, scanning electron microscopyenergy-dispersive X-ray spectroscopy, and other methods. The adsorption properties of SDS on PVB were investigated under different initial pHs, PVB doses, PVB particle sizes, contact times, initial SDS concentrations, and temperatures. The adsorption kinetic data were analyzed using pseudo-first-order, pseudo-second-order, Elovich, and intraparticle diffusion models. The results showed that the pseudo-second-order model fitted the adsorption data well, and the intraparticle diffusion was not the only control mechanism for PVB adsorption. The equilibrium data were analyzed with Langmuir, Freundlich, Temkin, and Dubinin–Radushkevich models. The results showed that the adsorption data conformed to the Langmuir model, and the maximum adsorption capacity of PVB for SDS was 40.5168 mg/g at 290.15 K. Moreover, the Dubinin–Radushkevich model illustrated that the adsorption process was chemisorption at low SDS concentrations and physical adsorption otherwise. The thermodynamic parameters showed that the adsorption of SDS on PVB was spontaneous and exothermic. In conclusion, the research results provide some basis for the PVB purification plant equipment.

Adsorption and Removal of Tetrabromobisphenol A by Adsorption on Functionalized Mesoporous Silica Nanotubes: Isotherms, Kinetics, Thermodynamics, and Optimization via Box–Behnken Design

In pursuit of environmental safety, a novel and efficient methoddispersive solid-phase extraction based on functionalized mesoporous silica nanotubes (FMSNT nanoadsorbent)was developed to remove tetrabromobisphenol A (TBBPA) from water samples. Characterization and comprehensive analysis of the FMSNT nanoadsorbent, including maximum adsorption capacity of 815.85 mg g–1 for TBBPA and its water stability, confirmed its potential. Subsequent analysis revealed the impact of multiple factors, for instance pH, concentration, dose, ionic strength, time, and temperature, on the adsorption process. The findings revealed that the adsorption of TBBPA followed the Langmuir and pseudo-second-order kinetics models while primarily driven by hydrogen bond interactions between bromine ions or hydroxyl groups of TBBPA and amino protons around the cavity. The novel FMSNT nanoadsorbent showed high stability and efficiency even after five times of recycling. Moreover, the overall process was identified as chemisorption, endothermic, and spontaneous. Finally, the Box–Behnken design was applied to optimize the results, confirming good reusability even after five cycles.
