The zeolitic imidazolate framework‐67 (ZIF‐67)‐based “pearl‐necklace‐like” composite membranes are prepared by in situ intergrown on the surface of 2‐methylimidazole/cellulose acetate (MIM/CA) electrospun nanofibers for the first time. With the aid of MIM, the ZIF‐67 nanocrystals successfully grow throughout the composites and attach to the fibers just like the pearls in necklace. The incubation time of ZIF‐67 has a significant influence on the structures and properties of the composites. And with an approximate saturation of ZIF‐67 nanocrystals, the integrated composites achieve a much higher surface area of 463.1 m2 g−1, which is as dozens of times as that of pure MIM/CA electrospun nanofibers (6.9 m2 g−1). In addition, the composites performed a high Cu(II) and Cr(VI) adsorption of 18.9 mg g−1 and 14.5 mg g−1, respectively. The adsorption data are well fitted with the pseudo‐second‐order kinetics. Moreover, adsorption mechanism is also discussed, and the electrostatic adsorption and ions exchange contribute to the high adsorption of Cu(II) and Cr(VI), and the existence of Cr(III) indicates that the Cr(VI) ions are partially reduced to Cr(III) during the adsorption. Therefore, the fabricated metal organic framework‐composite membrane with special “pearl‐necklace‐like” is a promising environmental material for removing heavy metal ions from water.

“…There are many reports that ZIFs were used as adsorbents to remove organic/inorganic contaminant from wastewater, and they showed a great potential application in wastewater treatment. In particular, ZIF‐67 exhibited excellent adsorption capability for the removal of several hazardous pollutants including Cr(VI) (Li, Gao, Ai, & Jiang, ), benzotriazole (Andrew Lin & Lee, ; Wang et al, ), methyl orange (Du et al, ; Yang et al, ), malachite green (Andrew Lin & Chang, ), phenol (Pan et al, ), and 1‐naphthol (Yan, Hu, Chen, Zhang, & Zhou, ). These studies suggested that hydrophobic pore and surface structure and the affinity of cobalt cation in ZIF‐67 were responsible for the excellent adsorption performance.…”

Fe 3 O 4 /ZIF-67 composite was successfully fabricated by a facile method and used as adsorbent to remove direct blue 80 (DB80, azo dye) from water. Characterizations of Fe 3 O 4 /ZIF-67 composite were performed by scanning electron microscopy (SEM), powder X-ray diffraction (PXRD), X-ray photoelectron spectroscopy (XPS), N 2 adsorption/desorption isotherms, Fourier transform infrared spectroscopy (FTIR), and magnetic property analysis. As an adsorbent, the factors (such as adsorbent dose, pH, initial concentration, contact time, and temperature) affecting the adsorption performance of adsorbent were investigated. The optimal adsorption condition is 5 mg of Fe 3 O 4 /ZIF-67 composite in 8 ml of DB80 solution (70 mg/L) for 60 min at 318 K, and the pH value has little effect on the adsorption performance. The adsorption isotherm, kinetics, and thermodynamics of DB80 adsorbed on the Fe 3 O 4 /ZIF-67 composite were also studied. The experimental results revealed that the experimental data followed the Langmuir model and the adsorption behavior could be well explained by pseudosecond-order kinetic model. Thermodynamic analysis indicated that the adsorption was a spontaneous and endothermic process. Furthermore, the mechanism of DB80 adsorbed on the Fe 3 O 4 /ZIF-67 composite was proposed. The occurrence of adsorption might be caused by the π-π stacking interaction between Fe 3 O 4 /ZIF-67 composite and DB80.
