Electrochemical Selective Detection of Cadmium and Mercury on Benzylpyrazolyl Naphthoquinone Modified Wax Impregnated Graphite Electrode

Abstract

A sensor probe has been synthesized with a facile one-pot reaction of molecules of 2-hydroxynaphthoquinone, P-Chlorobenzaldehyde and  3-methyl-1-phenyl-1H-pyrazol-5(4H)-one in water condition. These molecules were isolated as enol tautomers that exhibit intramolecular hydrogen bondMercury ion, Hg(II), has attracted extensive attention due to its highly toxic and bioaccumulative properties. As a result, this new phenyl benzopyrazole moiety is suited for use as a sensitive and selective “turn on” electrochemical sensor for Hg(II) ion
