? 2022Herein， a biomass-derived compound Z1 is synthesized via ‘one pot’ method for detection Pb2+ using fluorescence and visual dual-mode in aqueous solution。 Z1 shows good response to Pb2+ with a limit of detection (LOD) of 13。4 nM。 Importantly， the coordination mode of Z1 with Pb2+ is further evaluated by UV–vis and NMR spectroscopy and a 1:1 stoichiometry is identified。 Furthermore， Z1 can be applied to detection Pb2+ in practical samples with satisfactory recoveries in range of 96。0 %–112。0 % in real samples。 Besides， Z1 is added into polylactic acid (PLA) solution and made as portable fluorescence nanofiber membrane for Pb2+ detection。 Further， Z1 responds to Pb2+ with high selectivity and sensitivity and has been applied for tracking Pb2+ changes in soil samples， zebrafish， and plant tissues。 These results indicated that Z1 had great application potential in accurate detection Pb2+。
