Abstract : Vanillin-azine (VA), (4,4'-((1E,1'E)-hydrazine-1,2-diylidenebis(methane-ylidene))bis(2-methoxyphenol) has been synthesized from vanillin and tested as anion colorimetric chemosensors for sulfide anion. The VA was obtained from a condensation reaction between vanillin and hydrazine hydrate with a mol ratio of 2:1 mol for 24 h at room temperature. The structure was elucidated using FTIR, GC-MS, 1H-NMR, and 13C NMR spectrometers. The VA compound was examined as a colorimetric chemosensor for sulfide anion over several anions of CN-, F-, Cl-, Br-, I-, N3-, CH3COO-, and NO3-. The structure of the product showed agreement with all spectrometric data. The VA chemosensor tests indicated only selective to S2− anion followed by a color change from colorless to light blue in a DMF:HEPES buffer solution (DMF:HBS) medium (9:1, v/v, 10 mM, pH = 7.4). Filter paper strips can detect S2- anion with a color change from white to yellow. The VA chemosensor has a limit of detection (LOD) of 5.4 × 10-4 M, therefore, the VA chemosensor can be applied to detect S2- anion in tap water.
