“…The open frameworks in MOFs made them unique materials with extraordinary properties such as permanent porosity, stable framework, enormous surface area, and pore volume 2 . MOFs attracted significant attention in recent years due to their unique properties and potential applications in various fields 3 . MOFs have a high surface area and tunable pore size, which makes them attractive for gas storage and separation.…”

“…This is due to the simple design and operation of the system, flexibility of adsorbent materials for different contaminants, reusability of materials, and efficiency of the process special in low levels of pollutants. Despite drawbacks such as requiring adsorbent regeneration, adsorption is still an advantageous treatment technique that produces minimal sludge and polluted streams that are hard to handle 17 , 18 .…”

Metronidazole (MNZ) is an extensively used antibiotic against bacterial infections for humans and farm animals. Prevention of antibiotics discharge is essential to prevent adverse environmental and health impacts. A member of metal–organic frameworks, zeolite imidazole framework-67 with cobalt sulfate precursor (ZIF-67-SO4) and exceptional physio-chemical properties was prepared via room temperature precipitation to adsorb MNZ. The study framework was designed by Box–Behnken Design to evaluate the effect of pH, ZIF-67-SO4 dose, and contact time on adsorption efficiency. The polynomial model fitted the adsorption system indicated the optimal condition for 97% MNZ removal occurs at pH = 7, adsorbent dosage = 1 g/L, and mixing time = 60 min. The model also revealed that the removal increased with contact time and decreased at strong pH. Equilibrium and kinetic study also indicated the adsorption of MNZ followed the intra-particle diffusion model and the Langmuir isotherm model with a qmax = 63.03 mg/g. The insignificant loss in removal efficacy in use-reuse adsorption cycles reflected the practical viability of ZIF-67-SO4.

“…The imidazole ligand possesses two nitrogen centers; thus, it can act as an effective interactive attraction site for the copper ions to form a framework during the synthesis process. It was reported that the imidazole-derived ligands enhance the formation of porous metal-organic framework structures [60][61][62]. The formation of SSC-MOFs with interconnected stalks and spiky, spherical surfaces is recommended to enhance the dispersion of the SSC-MOFs in an aqueous solution and provide efficient contact with the entire sample extract during the microextraction process for the adsorption and preconcentration of arsenic(III) from water and food sample extracts.…”

Spiny-like spherical copper metal–organic frameworks (SSC-MOFs) were prepared and characterized via SEM, TEM, EDS, XRD, FTIR and the BET surface area. The fabricated SSC-MOFs were applied to develop a procedure for the microextraction of trace arsenic(III) for preconcentration. The results show that a copper- and imidazole-derived metal–organic framework was formed in a sphere with a spiny surface and a surface area of 120.7 m2/g. The TEM confirmed the perforated network structures of the SSC-MOFs, which were prepared at room temperature. The surface functional groups were found to contain NH and C=N groups. The XRD analysis confirmed the crystalline structure of the prepared SSC-MOFs. The application for the process of microextracting the arsenic(III) for preconcentration was achieved with superior efficiency. The optimum conditions for the recovery of the arsenic(III) were a pH of 7 and the use of a sample volume up to 40 mL. The developed SSC-MOF-derived microextraction process has an LOD of 0.554 µg·L−1 and an LOQ of 1.66 µg·L−10. The developed SSC-MOF-derived microextraction process was applied for the accurate preconcentration of arsenic(III) from real samples, including food and water, with the promised performance efficiency.
