Abstract

Metal-Organic Framework (MOF) was used as an adsorbent in the desalination process. In this study, MIL-53 Al was employed to remove ions from seawater. MIL-53 was prepared using Al(NO3)3�9H2O as a precursor, which dissolved with ethanol-water, then ligand was added by the ratio of metal to ligands 1:1.5. The crystallography of MIL-53(Al) was investigated using X-ray diffraction analysis to obtain a clear structure of crystals before and after activation. MIL-53(Al)(ht) ’s adsorption ability was tested for ions adsorption from seawater at 303 K. The removal efficiency of MIL-53(Al)(ht) toward multi-ion was 20.5% with an adsorption capacity of 147.7 mg ions/g MIL-53. The ions adsorption removal in MIL-53 (Al)(ht) follow the sequence of Cl+ > Na+ > SO4 2+ > Mg2+ > K+ > Ca2+. The reusability of MIL-53(Al)(ht) was also investigated, and the result indicated that its adsorption capacity significantly decreased after the 1st cycle of adsorption/desorption.
