“…MIL Al -101 is a representative of the broad family of MOFs, which is characterized by high porosity, stability, easy preparation, low cost, and surface functionality, making it an ideal choice for adsorption of contaminants 18 . Many researchers have proved the excellent performance of MILs toward the adsorptive removal of ibuprofen 19 , toxic dyes 20 , sulfacetamide 21 and ciprofloxacin 22 . Although MOFs-based adsorbents provide some advantages, however, their tendency to aggregate and lose during the recovery process is considered a respective drawback for their applications 23 .…”

In the present study, the magnetic NH2-MIL-101(Al)/chitosan nanocomposite (MIL/Cs@Fe3O4 NCs) was synthesized and used in the removal of azithromycin (AZT) from an aqueous solution for the first time. The as-synthesized MIL/Cs@Fe3O4 NCs was characterized by SEM, TEM, XRD, FTIR, BET, and VSM techniques. The effect of various key factors in the AZT adsorption process was modeled and optimized using response surface methodology based on central composite design (RSM-CCD). The low value of p-value (1.3101e−06) and RSD (1.873) parameters, along with the coefficient of determination > 0.997 implied that the developed model was well fitted with experimental data. Under the optimized conditions, including pH: 7.992, adsorbent dose: 0.279 g/L, time: 64.256 min and AZT concentration: 10.107 mg/L, removal efficiency and AZT adsorption capacity were obtained as 98.362 ± 3.24% and 238.553 mg/g, respectively. The fitting of data with the Langmuir isotherm (R2: 0.998, X2: 0.011) and Pseudo-second-order kinetics (R2: 0.999, X2: 0.013) showed that the adsorption process is monolayer and chemical in nature. ΔH° > 0, ΔS° > 0, and ∆G° < 0 indicated that AZT removal was spontaneous and endothermic in nature. The effect of Magnesium on AZT adsorption was more complicated than other background ions. Reuse of the adsorbent in 10 consecutive experiments showed that removal efficiency was reduced by about 30.24%. The performance of MIL/Cs@Fe3O4 NCs under real conditions was also tested and promising results were achieved, except in the treatment of AZT from raw wastewater.

“…Although the adsorptive properties of MOFs have been known for a very long time and extensively studied, the adsorption of such compounds has not been focused on until now. Metal-organic frameworks are used to adsorb gases [64,278,279] and even drugs, which have applications in water purification processes [280,281]. An interesting approach is the use of MOFs as materials that absorb cannabinoids and simultaneously serve their detection.…”

“…Most of the studies describe the efficient and selective adsorption of drugs from water, which is expected to highlight the potential for MOFs to be used in the environmental department, and more specifically for the treatment of pharmaceutical wastewater, which is currently a challenge [218,284,285]. The adsorption of 5-FU, caffeine (CAF) on ZIF-8 [286], brimonidine tartrate commonly used in eye diseases adsorbed on UiO-66, sulfacetamide [287] or sulfonamide antibiotics on MIL-101 (Cr) has been studied [281].…”

In recent years, the number of materials used as drug delivery systems (DDS) has increased dramatically. The widespread use of DDSs has improved both the safety and efficacy of therapy. The systems currently in use pose numerous drawbacks and require proper improvements. Although many modern materials are being developed, metal-organic frameworks (MOFs) deserve special attention. Thermal and chemical stability, high specific surface area, low toxicity, high biocompatibility, and great potential for modification are the main features enabling MOFs to be used as DDS. In this review, we describe MOFs, their structure, synthesis, and characterization, as well as drug loading, drug release kinetics, and bioassays. A critical approach is to outline the disadvantages as well as the limitations of MOFs and to identify areas that need to be studied more thoroughly. Nonetheless, the prospective nature of MOFs as DDS and potential adsorbents in overdose or poisoning is presented and highlighted.

New and effective methods of water purification are necessary to minimize pollution. Many methods have been used in wastewater treatment, but sorption is considered as an easy and economic process. The efficiency of any sorption process mainly depends on the physicochemical properties of the used adsorbent. Since photocatalysts can initiate reactions of decomposition organic contaminants under ultraviolet or sunlight irradiation without using chemicals or producing chemical wastes, photocatalytic reactions are considered a sustainable way to remove a variety of environmental pollutants. Ultraviolet water purification became the most effective method of water disinfection and purification. Heterogeneous semiconductor photocatalysts have recently emerged as an efficient material for purifying water. The crystal structure is crucial for photocatalytic activity and efficiency of semiconductors, thus optimal parameters must be provided during the preparation of photocatalysts. To overcome problems with semiconductors usage, the use of co-catalysts and photocatalyst carriers is one of the solutions. Recently, much emphasis has been placed on using graphene oxide (GO) supported semiconductor photocatalysts. In this paper, a short review of composites of titanium dioxide and graphene oxide-based materials is given.
