| Abstract: | A new fluorescence reagent, N,N-bi[4(1-pyrene)-butyroyl]-lysine (1) was synthesized. The new fluorescence sensor showed high sensitivity (detection limit up to 20.7 μg L−1) and specific selectivity for Pb2+ over other metal ions examined in aqueous solutions. It could also be used to remove Pb2+ from aqueous solutions by filtering the insoluble 1–Pb2+ complex with sufficient reversibility. |
