In this study, MIL-101(Fe), MIL-101(Fe,Cu), and graphene oxide (GO)/MIL-101(Fe,Cu) were synthesized to compose a novel sorbent. The adsorption properties of these three MOF-based composites compared toward the removal phosphate. Furthermore, influencing factors including time, pH, temperature, initial concentration on capacity phosphate materials as well reusability material discussed. structur...
Forward osmosis (FO) membrane is a promising technique. However, its application in desalination limited. Thus, we synthesized MIL-53(Fe)@γ-Al2O3 via solvent-thermal method to fabricate MIL-53(Fe)@γ-Al2O3/cellulose acetate (CA) composite membranes of high performance. and MIL-53(Fe) particles were studied using XRD, FITR, SEM, N2 adsorption-desorption isotherms, AFM. The structural features MIL...
Low-coverage adsorption properties of the metal-organic framework amino-MIL-53 (Al) were determined using the pulse chromatographic technique. By using n-alkanes, iso-alkanes, 1-alkenes, cyclohexane and benzene as probe molecules, the nature of the adsorptive interactions in amino-MIL-53 (Al) was studied. Henry adsorption constants and adsorption enthalpies of iso-alkanes are significantly lowe...
در این رساله به بررسی عملکرد غشاهای شبکه ترکیبی pmp/mil 53 و pmp/nh2-mil 53 در جداسازی گازهای co2/ch4 و co2/h2 پرداخته شده است. به منظور مشخصه¬یابی ذرات mof و غشاهای حاصله از روش¬های xrd، ft-ir، tga، dma، dls، sem،¬ bet و آزمون جذب گاز استفاده شد. همچنین خواص گاز تراوایی غشاها با عبور گازهای خالص و مخلوط¬های گازی و محاسبه تراوایی، گزینش¬پذیری¬های¬ ایده¬آل و واقعی و محاسبه ضرایب نفوذ و حلالیت سن...
Understanding the adsorption of water in metal−organic frameworks (MOF), and particularly in soft porous crystals, is a crucial prerequisite before considering MOFs for industrial applications. We report here a joint experimental and theoretical study on the behavior of a gallium-based breathing MOF, Ga-MIL-53, upon water adsorption. By looking at the energetics and thermodynamics of Ga-MIL-53,...
The synthesis on the gram scale and characterization of a series of flexible functionalized iron terephthalate MIL-53(Fe) type solids are reported. Chemical groups of various polarities, hydrophilicities, and acidities (-Cl, -Br, -CF(3), -CH(3), -NH(2), -OH, -CO(2)H) were introduced through the aromatic linker, to systematically modify the pore surface. X-ray powder diffraction (XRPD), molecula...
