Square wave voltammetric behaviour of N-benzylidene aniline and some of its derivatives in dimethyl sulphoxide

Abstract EN

The square wave voltammetric (SWV) behavior of eight substituted N-benzylidene anilines (I-VIII) C6H5-CH = N-C6H4R Where R = H, p-CH3, m-CH3, p-OCH3, m-OCH3, p- Cl, p-Br, and p-I respectively have been studied in Dimethyl sulphoxide (non aqueous medium) in presence of LiClO4( as supporting electrolyte).

All these compounds show a well defined one reduction peak with the exception of p-Br and p-I which show two reduction peaks appeared at potential Ep = -1.854, -1.894, -1.826, -1.916, -1.832 and - 1.732 Vs.

Ag / AgCl, KCl for compounds I-VI, respectively.

The peaks obtained are recommended for trace determination of these compounds.

Regression analysis on the standard curve for all compounds studied indicate a linear relationship between peak current and concentration over the range 3.8 x 10-6–1.5 x 10-4 M with a correlation coefficient of more than 0.99.
