Abstract
Three sulfadimidine metal complexes (MFe(III), Cu(II), and Ag(I)) were prepared, characterized, and examined as neutral carriers for the determination of SCNâ using modified carbon paste electrode. These sensors were successfully applied in the pure samples, and biological fluids. The electrode mechanism was investigated by UV-vis and FT IR. The experimental studies were complemented by quantum chemical calculations at DFT/B3LYP level of theory. The best performance was observed for Cu(II) electrode (C) containing 7.0% complex, 53.0% o-nitrophenyloctyl ether, 37.0% graphite and 3.0% cetylpyridinium chloride, and also for Fe(III)-electrode (A) having 6.0% complex, 52.0% o-nitro phenyloctyl ether, 40.5% graphite and 2.5% cetylpyridinium chloride.
