AB  - The oxidation of aniline with ammonium peroxydisulfate (APS) in aqueous solution of the plant-derived polyphenol, tannic acid, is reported. The effect of initial mole ratios [tannic acid]/[aniline] and [APS]/[aniline] on molecular structure, morphology, conductivity, and electroactivity of synthesized materials (PANI-TA) was investigated by UV-Vis, FTIR, Raman and EPR spectroscopies, scanning and transmission electron microscopies (SEM and TEM), conductivity measurements, and cyclic voltammetry, respectively. PANI-TA nanorods with the average diameter of 70-100 nm and conductivity of 1 x 10(-3) S cm(-1) were synthesized at [tannic acid]/[aniline] = 0.01 and [APS]/[aniline] = 1, while nonconductive, solid microspheres were obtained at [tannic acid]/[aniline] = 0.1 and [APS)[aniline] = 2. The mechanism of the early stages of simultaneous oxidation of aniline and tannic acid has been computationally studied by the RM1/COSMO method.

AB  - We report preparation of MnO2 composites with carbon (Vulcan, graphite, and carbonized nanostructured polyaniline 5-sulfosalicylate) via hydrothermal and low-temperature wet impregnation procedure. All prepared composites were characterized using thermogravimetric analysis. X-ray diffraction, scanning electron microscopy and conductivity measurements, and their characteristics compared. Furthermore, novel micro/nanostructured manganese dioxide/carbon composite based electrodes were tested for simultaneous determination of Pb2+ and Cd2+ as model analytes by anodic stripping voltammetry. The oxidation of the targeted heavy metals at the investigated composite electrodes gave distinctive and well separated peaks with lowest detection limits of 27 nM for Pb2+ and 52 nM for Cd2+ ions obtained with hydrothermally prepared MnO2/graphite composite based electrode.
