Abstract

A new hydrazone compound 2-methoxy-6-((E)-phenyldiazenyl)-4-((E)-(2-phenylhydrazineylidene) methyl)phenol (receptor R) based on vanillin has been synthesized and applied to cyanide anion detection in acetonitrile solvent. Color of the receptor solution turned from yellow to purple in the presence of cyanide anion and other anions like H2PO4-, Br-, CN-, SO42-, Cl-, I-, CH3COO- and F- could not effect color of receptor. Changing in the maximum wavelength of the receptor after addition of cyanide anion was confirmed by UV-Vis spectrophotometer. In the presence of cyanide, wavelength of the receptor changed from 347 nm to 510 nm. Detection limit of the receptor were also observed by UV-Vis spectrophotometer. Based on the UV-Vis titration, the receptor detected cyanide anions with limit of detection 4mM in the acetonitrile solvent.
