N2 - Abstract: A novel conjugated Schiff base-based chemosensor DAP, N′-((1E,2E)-3-(4-(dimethylamino)phenyl)allylidene)-3-nitrobenzohydrazide, has been synthesized. DAP showed significant selectivity toward mercury ion by color change of pale yellow to orange. Detection limit was 0.11 μM, which is lower than the value (2.48 μM) recommended by Health Canada. DAP could recognize and quantify mercury ion in real water samples. The binding mode of DAP and Hg2+ was demonstrated, based on Job plot, IR spectra and ESI-MS. Graphic abstract: A novel conjugated Schiff base-based chemosensor DAP was developed for the detection of mercury ion by color change of pale yellow to orange. DAP with low detection limit (0.11 μM) could quantify mercury ion in real water samples.[Figure not available: see fulltext.].
