Abstract

A Zr₆-based metal-organic framework (MOF), MOF-808, is investigated for the adsorptive removal of IO₃^- from aqueous solutions, due to its high surface area and abundance of open metal sites. The uptake kinetics, adsorption capacity and binding mode are studied, showing a maximum uptake capacity of 233 mg g^-1, the highest reported by any material.
