“…Based on the collected data, it is evident that the loading capacities of 2,4-D exhibited a significant increase as the pH level was raised from 2.0 (1.09 mmol/g) to 6.0 (1.21 mmol/g). This tendency is brought on by 2,4-D's limited solubility in acidic conditions and the fact that it exists in its difficult-to-adsorb molecular form [ 33 , 34 , 55 ]. Higher pH levels enhance the solubility and adsorption of 2,4-D as dissolved molecules because it is more hydrophilic.…”

“…In general, the procedure of different adsorption isotherms is foremost for understanding the mechanisms of adsorption and optimizing the design of the adsorption processes. Each isotherm gives unique data on the adsorption process and can identify the best adsorbent material and operating conditions for a particular application . The adsorption isotherm models of 2,4-D onto the MIL-88(Fe)-NH 2 adsorbent are presented in Figure .…”

Metal−organic frameworks (MOFs), a material known for its multifunctionality, chemical stability, and high surface area, are now commonly utilized as an adsorbent for water treatment. The MOF (MIL-88(Fe)-NH 2 ) was synthesized and used to remove the commonly used toxic herbicide 2,4-dichlorophenoxyacetic acid (2,4-D) from water. The MIL-88(Fe)-NH 2 MOF was fully characterized using multiple techniques. A systematic investigation was conducted to evaluate the key parameters that impact the adsorption process, which include coexisting anions, adsorbent dosage, and solution pH. The adsorption isotherm was fitted using the Langmuir model, while the kinetics were fitted using pseudo-second-order. The adsorption process was both chemisorption and endothermic. The capacity for adsorption increased with rising temperatures. The MIL-88(Fe)-NH 2 adsorbent has a maximum adsorption capacity of 345.25 mg g −1 for removing 2,4-D, significantly higher than previous adsorbents used for this purpose. The adsorption mechanism could be ascribed to hydrogen bonding, pore filling, π−π conjugations between the 2,4-D molecules and the MIL-88(Fe)-NH 2 adsorbent, and electrostatic interactions. Furthermore, the adsorption capacity of MIL-88(Fe)-NH 2 adsorbent showed only a slight decrease after five successive recycles, and it could be easily regenerated through solvent washing. When used in environmental water samples, especially those containing electronic wastes, the MIL-88(Fe)-NH 2 adsorbent demonstrated satisfactory adsorption capacity and reusability. The MIL-88(Fe)-NH 2 adsorbent is more practical and reusable and has better adsorption capacity and shorter equilibrium time compared to previously reported adsorbents.

This study looked at the doxorubicin hydrochloride (DOX) anticancer drug's adsorption characteristics on a silverbased metal−organic framework (Ag-MOF). X-ray diffraction (XRD), scanning electron microscopy (SEM), and X-ray photoelectron spectroscopy (XPS) were used for the characterization of Ag-MOF. The pore volume and surface area of Ag-MOF were determined through Brunauer−Emmett−Teller (BET) testing at 77 K to be 0.509 cm 3 /g and 676.059 m 2 /g, respectively. Adsorption at pH 6 was established to be the best for DOX compared to alkaline solution. Ag-MOF has a good capacity for eliminating DOX (1.85 mmol/g), according to adsorption experiments. From the adsorption results, we can find that Langmuir is the most fitted adsorption isotherm model and the pseudo-second order model best fitted the adsorption kinetics. The energy of activation for adsorption, which was determined to be 15.23 kJ/mol, also supported a chemisorption process. The mechanism of adsorption was evaluated, and details of all possible interactions between DOX and Ag-MOF were illustrated. On the other hand, while examining the impact of temperature, we identified the thermodynamic constraints as ΔG°, ΔH°, and ΔS°and confirmed that the reaction was an endothermic one and spontaneous. Even after numerous reuse cycles, the efficiency remained constant. The synthetic adsorbent was remarkably recyclable at a rate of more than 91.6%. By using the MTT assay, the cytotoxicity of the tested Ag-MOF and DOX@Ag-MOF against human breast cancer cells (MCF-7) was evaluated in vitro. The in vitro antimicrobial activity of Ag-MOF and DOX@Ag-MOF was also tested.
