Evaluation of Electrochemical and Biological Characteristics of Schiff Base N,N'-Benzene-1,2-Diylbis[1-(Pyrazin-2-yl)Methanimine] Complex of Palladium(II)
M. Uppal, G. Singh*

A palladium(II) complex of Schiff base N,N'-benzene-1,2-diylbis[1-(pyrazin-2-yl)methanimine] was synthesized and used for the selective determination of fluoride ion in various water, fruit juice and toothpaste samples. The selectivity calculated by mixed potential method indicates the high selectivity of the complex towards fluoride ion over other tested anions. The electrode based on DBP as plasticizer has a liner concentration range of 1.6 x 10-7 M – 1.0 x 10-2 M with lower detection limit of 5.2 x 10-7 M and has fast response time of about 10 s.
