“…Compared to the test with deionized water samples, the LOD obtained in drinking water remains about the same (1.68 vs 1.73 μM), while the LOD obtained with tap water samples is slightly higher, which us likely attributed to the presence of unidentified interferences (e.g., ions) in the tap water. Standard recovery experiments were performed, wherein PFOA solutions prepared in tap or drinking water were spiked as internal standards …”

A novel, water-stable, perylene diimide (PDI) based metal−organic framework (MOF), namely, U-1, has been synthesized for selective and sensitive detection of perfluorooctanoic acid (PFOA) in mixed aqueous solutions. The MOF shows highly selective fluorescence turn-on detection via the formation of a PFOA-MOF complex. This PFOA-MOF complex formation was confirmed by various spectroscopic techniques. The detection limit of the MOF for PFOA was found to be 1.68 μM in an aqueous suspension. Upon coating onto cellulose paper, the MOF demonstrated a significantly lower detection limit, down to 3.1 nM, which is mainly due to the concentrative effect of solid phase extraction (SPE). This detection limit is lower than the fluorescence sensors based on MOFs previously reported for PFAS detection. The MOF sensor is regenerable and capable of detecting PFOA in drinking and tap water samples. The PDI-MOF-based sensor reported herein represents a novel approach, relying on fluorescence turn-on response, that has not yet been thoroughly investigated for detecting per-and polyfluoroalkyl substances (PFAS) until now.
