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.
