Adsorptive Removal of Iodate Oxyanions from Water using a Zr-based Metal–Organic Framework

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, the highest reported by any material.
