This work describes the preparation and characterization of size-controlled zinc hexacyanoferrate (III) nanoparticles (ZnH). They were prepared using different proportions of water/formamide in the complexation reaction of Zn 2+ with [Fe III (CN) 6 ] 3À. The materials were characterized by Fourier Transform Infrared Spectroscopy (FT-IR), Ultraviolet-Visible Spectroscopy (UV-vis), X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Energy Dispersive X-ray Spectroscopy (EDX) and Cyclic Voltammetry (CV). The cyclic voltammograms of the modified graphite paste electrode with ZnH-1, ZnH-2, ZnH-3 and ZnH-4 showed a well-defined redox couple with formal potential (E u 0) = 0.94 AE 0.01 V (n=20 mV s À1 ; KCl 1.0 M)) attributed to the redox process [Fe II (CN) 6 ]/[Fe III (CN) 6 ] in the presence of Zn 2+. The dependence of particle size on the detection of sulfite was verified.
The present work reports the voltammetric behavior of Zinc hexacyanoferrate (III) nanoparticles and their application in the detection of N-acetylcysteine. Two distinct ratios of water/formamide 10:0 (ZnH-1) and 4:6 (ZnH-2) were studied in the complexation reaction of Zn
A novel composite obtained from reaction of zirconium (IV) phosphated (ZrP) with Ag + and subsequent interaction of potassium hexacyanoferrate (III) (ZrPAgH) was prepared and characterized by infrared spectroscopy (FTIR) and cyclic voltammetry. The graphite paste electrode modified with ZrPAgH exhibited a cyclic voltammogram with a redox couple with midpoint potential E
This paper describes the interaction of a octa (3-chloropropyl)octasilsesquioxane (SS) functionalized with imidazole (SSI) groups, and its subsequent reaction with silver (AgSSI) and hexacyanoferrate (III) (AgHSSI). The materials SS, SSI were characterized by infrared (FTIR); solid state 13 C and 29 Si nuclear magnetic resonance (NMR). The AgSSI and AgHSSI were characterized by electronic (Uv-Vis) and infrared spectroscopy (FTIR). The AgHSSI was incorporated into a graphite paste electrode and the electrochemical studies were conducted with cyclic voltammetry. The AgSSI system was studied first, followed by the AgHSSI. The spectroscopic studies reveals that preparation was conducted with success.
