Abstract

The present study introduced a novel ion-pair complex of [Co(5,5 '-dmbpy)(3)][Ce(NO3)(6)] (a1) fabricated by the reaction of Co(NO3)(2)center dot 6H(2)O, Ce(NO3)(3)center dot 6H(2)O, NaNO3 and 5,5 '-dimethyl-2,2 '-bipyridine ligand. A sonochemical method was used to synthesize the nano-scale [Co(5,5 '-dmbpy)(3)][Ce(NO3)(6)] (a2). The sulfite was then detected and quantified on a carbon paste electrode (CPE) modified with ferrocene derivative and cobalt nanoparticles (Co-NPs). Scanning electron microscopy (SEM) and X-ray powder diffraction (XRD) were employed to characterize the Co-NPs. The results showed a significant improvement in the electrocatalytic activity and electro-active surface area following the CPE surface modification with the ferrocene derivative and Co-NPs. The voltammetric detection of sulfite was performed successfully by the as-fabricated sensor in real samples, with the linear dynamic range and the limit of detection of 0.07-440.0 and 0.03 mu M, under optimal conditions, respectively.
