In this study, a biomass-derived compound Z1 was synthesized via a 'one pot' method and applied for dual-mode Pb2+ detection in aqueous solution. Z1 showed good response to Pb2+ with a detection limit of 13.4 nM. Additionally, Z1 was fabricated into a portable fluorescence nanofiber membrane and successfully used for Pb2+ detection in various samples.
Herein, a biomass-derived compound Z1 is synthesized via 'one pot' method for detection Pb2+ using fluores-cence 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+.
