摘要：

A selective adsorptive method using metal-organic frameworks (MOFs) was employed for removal of 3-MCPD and glycidol, which are potential genotoxic carcinogens. To optimize adsorption performance, a series of Fe MIL-88 s with different ligand types were used with further modification by sequential carboxylation and deprotonation processes. Among these ligands, the MOFs, consisting of 2,6-naphthalenedicarboxylic acid (FeMIL-88_BDC) showed the best adsorption performance. A rapid efficiency improvement of 3-MCPD and glycidol was observed after its surface modification. Despite lacking superior porosity, deprotonated Fe-MIL-88_BDC showed the highest adsorption capacity of the reported adsorbents. We found that the remarkable improvement in adsorption efficiency was due to esterification with carboxyl groups on 3-MCPD and glycidol. This adsorption performance was seen only in 3-MCPD ester and glycidyl ester (as a precursor of 3-MCPD and glycidol) in palm oil without a change of fatty composition and minor components.
