“…In particular, metal-organic frameworks (MOFs) are known to contain extremely small pores of nanometer scale, 16 exhibit well-ordered porous structures and chemical functionalities, have large specic surface areas, high pore volumes, adjustability of pore channels and offer directional modication of functional groups. [17][18][19] All of these characteristics suggest that MOFs are potential materials for cleaning phosphoruscontaminated water. Liu et al successfully prepared La-MOFs which could adsorb phosphate from aqueous solution, but a large amount of organic solvent (DMF) was used in the synthesis method, which is very unfriendly to the environment.…”

“…These results suggested that the Langmuir model could better represent the TC adsorption process. The adsorption of TC onto MOF-818 was dominated by monolayer adsorption and chemical adsorption might play the main role in the process of TC adsorption [44].…”

“…In comparison, MOFs have chemical and thermal stability, ease of structural functionalization, large specific surface area, and high porosity. More importantly, the pore sizes can be controlled and affinities toward pollute molecules including coordination bond, π-π interactions, hydrogen bonding and electrostatic interactions can also be designed on purpose [42][43][44][45]. Therefore, MOFs have been identified as one of the most efficient adsorbents.…”

MOF-818, a mesoporous cage metal-organic framework, was investigated for the removal of tetracycline hydrochloride (TC) from aqueous environment. The product was characterized by XRD, BET, FESEM, FT-IR, XPS and TGA. The influence of different parameters such as solution pH, contact time, temperature, adsorption dosage, initial TC concentration on the adsorption capacity was investigated. The as-prepared MOF-818 showed rapid removal of TC and with maximum saturated adsorption capacity calculated to be 442.5 mg g −1 at pH 3.32, 323 K. The adsorption isotherms were fitted by Langmuir, and Freundlich models. The kinetic data was analyzed by pseudo-first-order, pseudo-second-order, and intraparticle diffusion models. The TC adsorption process followed pseudo-second-order kinetics and best fitted the Langmuir adsorption model. The thermodynamic data showed that the adsorption was a spontaneous and endothermic reaction. A mechanism for TC adsorption was proposed and the chemisorption and π-π interaction was believed to direct the interaction between MOF-818 and TC molecules.

In this study, adsorption of hexavalent chromium has been examined on ZIF-8 and its various composites. ZIF-8 was modified by using amine groups, GO and Mg(OH) 2 /GO. ZIF-8, Mg(OH) 2 /GO, ZIF-8/NH 2 , ZIF-8/Mg(OH) 2 /GO, ZIF-8/NH 2 /GO and ZIF-8/NH 2 /Mg(OH) 2 /GO was studied for Cr(VI) adsorption Several characterization techniques were used for the structural and surface characterization such as Fourier transform infrared spectroscopy (FTIR), x-ray diffraction (XRD), scanning electron microscopy (SEM), and Brunauer-Emmett-Teller (BET) surface area analyzer. The impact of various adsorption parameters (contact time, pH, initial concentration of Cr(VI) and absorbent dosage) was studied in batch experiments. Different kinetic and isotherm models were applied on equilibrium data. The adsorption process of ZIF-8 and its composites was explained by pseudo-second-order kinetic model as well as Langmuir isotherm, with maximum removal efficiency of 98% for Cr(VI) by ZIF-8/NH 2 /Mg(OH) 2 /GO.
