“…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.

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.

“…This unique feature, combined with their flexible pore size, makes MOFs suitable for gas sorption, chemical sensing, and catalysis. Recently, MOFs have emerged as a distinguished medium for biomedical applications, especially drug delivery [26–36] .

Biomolecule‐incorporated metal‐organic frameworks (b‐MOFs) exhibit enhanced bioavailability and biocompatibility, making them an ideal option for use as drug delivery vehicles. While b‐MOFs possess outstanding drug loading and release capabilities, their microscale crystal sizes restrict their applicability as nanocarriers and drug delivery systems. To overcome this limitation, this paper presents a microwave‐irradiation‐based technique for the synthesis of porous adenine‐incorporated Zn‐based MOFs with particle sizes of approximately 200 nm as paclitaxel nanocarriers. The nanomaterial demonstrated a substantial paclitaxel loading capacity of 637 mg g−1. Moreover, it effectively increased the solubility of paclitaxel by 2.5‐fold compared to that of the free form. Thus, the nano MOF is a promising delivery vehicle for paclitaxel. Notably, the paclitaxel‐loaded nano MOF exhibited higher toxicity toward cancer cells than the free drug, further highlighting its potential as an effective anticancer agent.
