“…In most cases, MOFs adsorb organic pollutants through π‒π interactions. Thus, modifying MOFs by adding additional organic groups such as ‒NH 2 , ‒COOH, or ‒SO 3 H as functionalization could improve their adsorption capacity by providing an additional interaction through electrostatic attraction or hydrogen bonding [ 65 , 66 , 67 , 68 , 69 , 70 , 71 , 72 ]. Furthermore, ligand functionalization of MOFs could also enhance their pollutant adsorption selectivity, stability, and reusability.…”

The accumulation of pollutants in water is dangerous for the environment and human lives. Some of them are considered as persistent organic pollutants (POPs) that cannot be eliminated from wastewater effluent. Thus, many researchers have devoted their efforts to improving the existing technology or providing an alternative strategy to solve this environmental problem. One of the attractive materials for this purpose are metal-organic frameworks (MOFs) due to their superior high surface area, high porosity, and the tunable features of their structures and function. This review provides an up-to-date and comprehensive description of MOFs and their crucial role as adsorbent, catalyst, and membrane in wastewater treatment. This study also highlighted several strategies to improve their capability to remove pollutants from water effluent.

“…According to the experimental results, the adsorption kinetics and isotherms data of tetracycline on MOF 1 indicated that the pseudo second-order kinetic and Langmuir models best described the adsorption process. We speculate that there are π-π interactions, electrostatic interactions and hydrogen bonding between tetracycline and MOF 1 [32,38,39]. This seems plausible since tetracycline contains multiple phenolic hydroxyl groups and plentiful conjugated benzene ring structures which can interact via hydrogen bonding and π-π interactions with the benzene ring and pyridine rings of MOF 1.…”

Serious environmental and human health problems caused by the abuse of antibiotics have attracted worldwide concern. Recently, metal–organic frameworks (MOFs) with high porosity have drawn wide attention for their effects in the adsorption and removal of pollutants from complex matrices. Herein, a high-stable metal organic framework (MOF), i.e., ((ZnCl2)3(L)2·DMF)n, where L=1,3,5-tris((pyridin-4-ylthio)methyl)benzene), MOF 1, was applied to adsorb and remove tetracycline from sewage and dairy products. The results showed that MOF 1 exhibited a strong performance in the adsorption of tetracycline. The effects of initial pH values, adsorbent dose, contact time and ionic strength of the adsorption performance of MOF 1 were investigated. The adsorption kinetics best fit the pseudo-second order model, and the adsorption isotherms matched the Langmuir adsorption model well. It was indicated that both chemical adsorption and physical adsorption play an important role in the adsorption process, and the adsorption of tetracycline was homogeneous and occurred on a monolayer on the surface of MOF 1. Additionally, the stability of MOF 1 and the details of the adsorption mechanism were also investigated. Thus, this study provides a new candidate for the application of MOFs-based adsorbents in the removal of antibiotics from sewage and dairy products.

“…Notably, owing to the unique characteristics of MOFs such as water stability, ultrahigh porosity, easy functionalization, thermal stability and high surface area, MOFs have successfully been utilized for the adsorptive removal of heavy metals 15 , pharmaceutical contaminants 16 and synthetic dyes 17 . One of iron-based MOFs that has been exhibiting notable adsorptive behavior is MIL-53 owing to its structure flexibility, stability in water and chemical stability 18 . Furthermore, MIL-125 is one more bright member in MIL-family that possesses promising photo-catalytic and adsorptive behavior due to its photo-reactivity, thermal and chemical stability, etc.…”

During the turbulent period of COVID-19, the medical staff is exerting great efforts to preserve humanity. However, the tons of pharmaceutical residues especially antibiotics that is being disposing daily into water bodies may be the seed to an even more ferocious pandemic. Thence, it is inevitable to find out effective strategies for removing these noxious pharmaceutical residues from water. We aimed in this investigation to fabricate easy separable composite microbeads for efficient adsorption of tetracycline (TC) drug. Herein, MIL-125/MIL-53 binary metal organic framework (MOF) was synthetized and incorporated with carbon nanotube (CNT) into alginate (Alg) microbeads to form MIL-125/MIL-53/CNT@Alg composite microbeads. Various tools including FTIR, XRD, SEM, BET, Zeta potential and XPS were applied to characterize the composite microbeads. The results revealed that the adsorption of TC was augmented with rising TC proportion up to 15 wt% in the microbeads matrix. In addition, the adsorption process followed the pseudo-second-order and well-fitted to Freundlich and Langmuir models with a maximum adsorption capacity of 294.12 mg/g at 25 ◦C, while the adsorption process was endothermic, randomness and spontaneous. Besides, reusability test signified that MIL-125/MIL-53/CNT@Alg composite microbeads retained admirable adsorption properties for six consecutive cycles, emphasizing its potentiality for removing of pharmaceutical residues.
