Abstract: A method for preparing metal-organic framework including reacting a mixture having metal precursor and polyethylene terephthalate plastic using microwave synthesis and to metal-organic framework prepared therefrom. The method for preparing metal-organic framework can utilize polyethylene terephthalate plastic waste, thus this can help reduce environmental problems. Additionally, the method can be conveniently performed without complicated and complex steps, as well as save energy in preparation.

Abstract: The present invention relates to a zirconium-based metal organic framework comprising at least a tetravalent zirconium ion (Zr4+) and a bidentate or tridentate linking ligand bonding the said tetravalent zirconium ion (Zr4+). Moreover, the present invention also relates to a method for preparing the zirconium-based metal organic framework comprising the steps of: (a) preparing a reaction mixture comprising a zirconium compound, a linking ligand and, optionally, a modulating agent in a solvent; (b) heating the reaction mixture obtained from step (a); and (c) washing a reaction product obtained from step (b) with the solvent and drying the reaction product. The zirconium-based metal organic framework according to the present invention is suitable for using in a process for removing heavy metals in the condensate, especially using in the adsorption, removal, or reduction of arsenic and mercury contents in the condensate.
