“…Therefore, a promising method for dehydrating isopropanol is pervaporation, which makes it possible and easy to extract water without any additional chemical reagents by the right choice of membrane based on hydrophilic polymers. Polyvinyl alcohol (PVA) [ 11 , 13 ], sodium alginate (SA) [ 9 , 14 , 15 , 16 , 17 ], polyvinyl amine [ 18 ], chitosan [ 19 , 20 , 21 ], poly(ionic liquid) complex (PILC) [ 22 ], etc. have been already investigated as a membrane materials for pervaporation dehydration of isopropanol.…”

The application of environmentally friendly and energy-efficient membrane processes allows improvement the ecological safety and sustainability of industrial production. However, the effective application of membrane processes requires novel high-performance thin film composite (TFC) membranes based on biopolymers to solve environmental problems. In this work for the first time novel thin film nanocomposite (TFN) membranes based on biopolymer chitosan succinate (ChS) modified with the metal organic framework iron 1,3,5-benzenetricarboxylate (Fe-BTC) were developed for enhanced pervaporation dehydration. The formation of a selective layer of TFN membranes on the porous membrane-support was carried out by two methods—dynamic technique and physical adsorption. The effect of the membrane formation method and Fe-BTC content in ChS layer on the structure and physicochemical properties of TFN membranes was investigated. The developed TFN ChS-based membranes were evaluated in the pervaporation dehydration of isopropanol (12–30 wt.% water). It was found that TFN ChS-Fe-BTC membranes prepared by two methods demonstrated improved permeation flux compared to the reference TFC ChS membrane. The best transport properties in pervaporation dehydration of isopropanol (12–30 wt.% water) were possessed by TFN membranes with 40 wt.% Fe-BTC prepared by dynamic technique (permeation flux 99–499 g m−2 h−1 and 99.99% water in permeate) and TFN membranes with 5 wt.% Fe-BTC developed by physical adsorption (permeation flux 180–701 g m−2 h−1 and 99.99% water in permeate).

“…We conducted FTIR characterization of the prepared Fe III -HMOF-5 and Fe III -HMOF-5/capsaicin to determine whether new chemical bonds were formed before and after adsorption. As shown in Figure 3 , the spectrum of capsaicin showed a clear peak of CH 2 at 2,900 cm −1 ( Kuzminova et al, 2021 ). The spectrum of Fe III -HMOF-5 showed a clear presence of -OH, while the spectrum of Fe III -HMOF-5/capsaicin showed a significant weakening of the -OH peak.…”

The content of capsaicin can be used as exotic markers of kitchen recycled oil. In this study, a bimetallic MOF nanocage (FeIII-HMOF-5) was successfully prepared by a one-step solvothermal method and used for electrode modification to prepare a highly sensitive electrochemical sensor for rapid detection of capsaicin. Capsaicin could be selectively immobilized onto the FeIII-HMOF-5 surface during infiltrating adsorption, thus exhibiting very excellent sensing performance. The detection conditions of the sensor were optimized. Under optimum conditions, the electrochemical sensor can linearly detect capsaicin in the range between 1–60 μM with a detection limit of 0.4 μM. In addition, the proposed electrochemical sensor showed excellent stability and selectivity. The real sample tests indicated the proposed electrochemical sensor was comparable to conventional UV spectrophotometry.

Metal-organic frameworks (MOFs) are porous crystal frameworks constructed by metal clusters and bridging organic ligands. [1] This class of materials not only has a highly tunable and regular pore structure, variable functionality, and internal connectivity, [2] but the superior designability enables them to accommodate the introduction of a variety of functional sites on frames, cavities, and channels. [3] These make them have important applications in many fields, including drug delivery, [4] adsorption, [5] antimicrobials, [6] electron conduction, [7] gas storage, [8] catalysis, [9] sensing, [10] and energy conversion. [11] MOFs were first developed by Hoskins and Robson via connecting discrete metal clusters and reappraising the Zn(CN) 2 and Cd(CN) 2 structure [12] and then termed MOFs in 1995. [13] Recent researches focus on the modulation of MOF chemistry to expending our understanding of the relationship between the MOFs structure, function, and applications. However, the poor adhesion and heterogeneous distribution of powdery MOFs hindered their detection in many applications. So, the development of the commercialization of MOFs was limited. [14] Membrane is a kind of material with small pore size and large specific surface area. [15] A series of structural features facilitate its rapid transfer of matters with the action of external driving forces in the field of biomedical, [16] energy storage, [17] and environmental protection. [18] The preparation of MOFs into membranes will play their role to the maximum extent [14,19] and endow more precisely pore size, pore structure, and molecular-/ion-specific groups with the membranes. [20] MOF membranes are mainly divided into two categories: pure MOF membranes and MOF/polymer hybrid membranes. Pure MOF membranes are the continuous thin layers of MOFs that are formed by growing (or depositing) on a porous support layer and/or inorganic substrate or a porous polymer substrate. These kinds of MOF membranes have the advantages of good thermal stability, high mechanical property, antifouling, antiswelling, and controllable pore structure. [21] As pure MOF membranes are composed of MOFs, the permeability and selectivity are completely determined by the pore sizes of MOFs, which endow pure MOF membranes with significant selectivity. [22] Pure MOF membranes should have the best performance in theory. However, their brittle texture, high cost, and difficulty in chemical modification still limit their practical applications. MOF/polymer hybrid membranes are composite materials that are composed of a dispersed phase (MOFs) and a continuous phase (polymer or another flexible matrix). There are two forms: MOFs embedded in the polymer matrix and MOFs on the surface of the flexible substrate. The thickness is much thicker than the diameter of the embedded porous MOFs; thus, the doped MOFs are surrounded by the polymer matrix. In this case, the selectivity and permeability of the MOF/polymer hybrid membranes are significantly dependent on the properties of the
