Fluorescence detection of phosphate in an aqueous environment by an aluminum-based metal-organic framework with amido functionalized ligands
文献摘要：
The on-site monitoring of phosphate is important for environmental management.Conventional phosphate detection methods are not appropriate to on-site monitoring owing to the use of complicated detection procedures,and the consequent high cost and maintenance requirements of the detection apparatus.Here,a highly sensitive fluorescence-based method for phosphate detection with a wide detection range was developed based on a luminescent aluminum-based metal-organic framework(Al-MOF).The Al-MOF was prepared by introducing amine functional groups to conventional MIL to enhance phosphate binding,and exhibited excellent fluorescence properties that originated from the ligand-to-metal charge transfer(LMCT).The detection limit was as low as 3.25 μmol/L(0.10 mg/L)and the detection range was as wide as 3-350μmol/L(0.10-10.85 mg/L).Moreover,Al-MOF displayed specific recognition toward phosphate over most anions and metal cations,even for a high concentration of the co-existent ions.The mechanism of phosphate detection was analyzed through the characterization of the combination of Al-MOF and phosphate,and the results indicated the high affinity between Al-O and phosphate inhibited that the LMCT process and recovered the intrinsic fluorescence of NH2-H2BDC.The recovery of the developed detection method reached a satisfactory range of 85.1％-111.0％,and the feasibility of on-site phosphate detection was verified using a prototype sensor for tap water and lake water samples.It was demonstrated that the prepared Al-MOF is highly promising for on-site detection of phosphate in an aqueous environment.
