Novel cyclic voltammetry behavior of 3-((benzothiazol-2- diazenylnaphthalene-2,7-diol and use it for spectrophotometric determination of copper (II )in honey sample

The azo reagent 3-((benzothiazol-2-diazenylnaphthalene-2,7-diol] was synthesized and characterized by FT-IR ,1H-NMR
and
13CNMR spectral techniques. The electrochemical behavior of the azo reagent and its complex with Cu (II) has been
studied at glassy carbon disk GCE electrode in different supporting electrolyte at concentration (1M) and scan rate
(100mv.s
-1). Spectrophotometric determination of copper (II ) is based on the formation of a 2:1 complex with above
reagent. The complex has λmax at(588) nm and Ԑmax of( 1.436×10
4)L.mol-1.cm-1 .
A linear correlation (0.1 – 3.0 μg. ml
-1) was found between absorbance at λmax and concentration . The effect of diverse
ions on the determination of copper (II) to investigate the selectivity of the method were also studied . The stability
constant of the product was (1.1×10
8 ) . The proposed method was successfully applied to the analysis of honey sample .
