Adsorptive removal of bisphenol-A (BPA) using a MOF, Cr-benzenedicarboxylate (MIL-53), has been studied to understand the applicability of MOFs for the removal of hazardous endocrine disturbing chemicals from water. MIL-53 shows very fast adsorption in an hour and the adsorption capacity of MIL-53 is higher than that of activated carbon. Importantly, the adsorption of BPA over MIL-53 is very favorable especially at very low concentrations of BPA. Therefore, MOFs such as MIL-53 can be one of adsorbents that may be used in the adsorptive removal of BPA from contaminated water.
