[28] For Fe 3 O 4 -NHSO 3 H@H-KUST-1 (Figure 3b), in addition to the peaks that are related to Fe 3 O 4 @SiO 2 -NHSO 3 H, the asymmetric stretching vibration at 2927 cm −1 was attributed to the aromatic ring C-H in H3BTC, the absorption peaks of the C O bonds (1633 cm −1 ), and the stretching vibration peaks of C C bonds on the benzene ring (1442 and 1373 cm −1 ) [29] were observed, indicating the formation of the surface of HKUST-1.

A magnetic metal‐organic framework (MOF) nanocomposite was successfully prepared by a new and green strategy through reasonable design. Magnetic MOF of Fe3O4‐NHSO3H@HKUST‐1 nanocomposite use for removal of lead ions as an environmental pollutant. The experimental results indicated that the nano adsorbent of Fe3O4‐NHSO3H@HKUST‐1 can removed lead ions under optimum operational conditions. The dosage of the nanocomposite, pH of the sample solution, and contact time were obtained to be 10 mg, 7.0, and 90 min, respectively, while the initial concentration of Pb(II) ions of 400 mg/L was used. A kinetic study indicated that a pseudo‐second‐order model agreed well with the experimental data. The isotherm experiments revealed that the Langmuir model attained better fits to the equilibrium data than the Freundlich model. The maximum adsorption capacity of the adsorbent for the removal of lead under the optimum operational conditions of pH 7.0 and temperature 25°C was found to be 384.6 mg/g. The thermodynamic parameters indicate that the adsorption of lead is spontaneous and endothermic. The magnetic MOF nanocomposite could be recovered easily and reused many times without significant loss of its nano‐adsorbent activity. The proposed method is simple, eco‐friendly, low cost, and efficient in the removal of lead ions from aqueous solutions.

BACKGROUND Tannin‐immobilized cellulose (T/C) microspheres were fabricated by a facile homogeneous reaction in a water/oil (W/O) emulsion for the removal of cationic dye from aqueous solution. The microspheres were characterized by scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR) and Zeta potentials test. Setting methylene blue (MB) as a cationic dye model, the adsorption isotherms, kinetics and effect factors of MB adsorption were investigated to evaluate the effectiveness for dye removal. RESULTS The microspheres exhibited porous structure. Cellulose contributed to provide a support for the porous structure, and immobilized tannins acted as adsorbent sites which combined with MB by electrostatic attraction, resulting in the attractive adsorption ability of T/C microspheres. Microspheres exhibited rapid adsorption rate even when the initial MB concentration was 1500 mg L−1. The pseudo‐first‐order, pseudo‐second‐order and intraparticle diffusion models were used to fit adsorption data in the kinetic studies. Results indicated that the adsorption kinetic was more accurately described by the pseudo‐second‐order model. It has been demonstrated that the better agreement was with the Langmuir isotherm with correlation coefficient >0.9996. Regeneration experiments showed that T/C microspheres can be reused at least three times without obvious loss of their original adsorption capacity. CONCLUSION The results revealed that the T/C microspheres can be considered as a stable and effective adsorbent for cationic dye removal from industrial effluents. Tannin immobilization and material forming were simultaneously implemented by a facile homogeneous reaction in W/O emulsion, providing a new pathway to fabricate tannin‐immobilized materials for water treatment. © 2016 Society of Chemical Industry

“…Few studies about dye adsorption on HKUST‐1 have been reported and are summarized in Table . Nevertheless, the subtle aqueous stability reported for HKUST‐1 alone, has been employed for interactions with various types of dyes such as Congo red, Methylene blue, Crystal violet, Basic Fuchsin and Eriochrome black T with interesting results in their experimentations, as can be seen in Table . Moreover, HKUST‐1 in combination with other materials has provided an important strategy for generating long lasting composites in liquid (aqueous) phase.…”

The metal–organic framework (MOF) HKUST‐1 was employed as an interaction matrix for fundamental loading studies of anthraquinone dyes. Chosen dyes were alizarin (A), alizarin S (AS), disperse blue 1 (B1), disperse blue 3 (B3), disperse blue 56 (B56) and purpurin (P). All materials were characterized by XRD, FTIR, TGA and SEM. Hence the interaction of dyes with the framework was characterized by theoretical–experimental differential analysis. One‐pot loading strategy resulted in more efficient scavenging of dyes, and reached 100 % for B56 using 50 mg L−1. SEM revealed important microstructural changes, the smaller crystals ranged 0.8–3 μm in size and almost all composite sizes were from this to higher values, reaching 70 μm, with varying shapes. Two composites were larger in size range (about 2500–1000 μm), and were shaped as rods, octahedrons and coffin lids. Indeed, the microstructure could be modulated depending on preparation conditions and type of loaded dye. For the higher loading series, N2 adsorption and XPS experiments were carried on to further evidence dye–MOF interactions. Ab initio prediction of structural properties for A@HKUST‐1 and P@HKUST‐1 were obtained by means of solid‐state CRYSTAL14 code at the PBE0 level of theory. Computed findings evidenced two O→Cu coordinative bonds, one from O‐ketone and the other from O‐phenolate moiety as main interactions towards CuNET centers.
