“…These materials make it possible to visually determine the presence of metal ions in a multi‐mixture solution that does not require a costly apparatus. Metal–organic frameworks (MOFs), multifunctional porous crystalline materials, are made up of coordination bonds between metallic ions and organic ligands 22–24 . Due to their high specific areas, adjustable architectures, and superior chemical or thermal stabilities, 25,26 they play significant roles in a variety of sectors, including biomimetic catalysis, 27–29 drug delivery, 30 gas storage, 31 and biosensors 32,33 .…”

Generally, aluminum exposure is not a risk; however, long‐term and high‐intensity exposure can have a negative impact on health. The ligand‐embedded MOF was developed for high sensitivity in the detection and removal of Al (III) ions in aqueous solutions. Novel selective metal–organic framework was synthesized via strong covalent attachment of NH2‐MIL‐53(Al) and 2‐hydroxy naphthaldehyde (2‐HNA) for selective and efficient fluorometric sensing of Al (III) ions. The elemental structure and morphology of the fabricated sensor (2‐HNA = N‐MIL‐53[Al]) were thoroughly evaluated to understand the high selectivity and considerable fluorescence stability in the water. The intensity of the sensor fluorescence increased linearly as the concentration of Al (III) increased from 0.19 to 2.0 ppm with a detection limit of 33.1 ppb (1.23 × 10−6 M) and 5 s of response time at pH 7. The potential mechanism is discussed. The high selectivity of the developed chemosensor was achieved against various competing environmentally relevant metal ions. Furthermore, Al (III) ions were successfully quantified in tap water, wastewater, human serum, and tea samples. The high precision (RSD percent, 0.009–1.76) and excellent accuracy (recovery percent, 99.96–101.56) of the 2‐HNA = N‐MIL‐53 (Al) sensor indicated that it holds great promise for the ultrafast and highly selective determination of Al (III) ions in wastewaters, with high reproducibility and reversibility.
