Nanostructured materials for sensing Pb(II) and Cd(II) ions: Manganese oxohydroxide versus carbonized polyanilines?
Nanostructured materials including three different carbonized polyanilines and manganese oxyhydroxide were prepared and evaluated as electrode materials for sensing of lead and cadmium ions in aqueous media. Anodic stripping voltammetry results indicated that all prepared materials could be...

| Summary: | Nanostructured materials including three different carbonized polyanilines
and manganese oxyhydroxide were prepared and evaluated as electrode materials
for sensing of lead and cadmium ions in aqueous media. Anodic stripping
voltammetry results indicated that all prepared materials could be
successfully used for determination of these two heavy metal ions. Carbonized
polyaniline-based electrodes have higher signal and lower limits of detection
(10-7 М) compared to manganese oxyhydroxide-based electrode. Among the three
studied carbonized polyanilines, the one that was derived from polyaniline
precursor produced in the presence of 3,5-dinitrosalicyclic acid showed the
highest electrocatalytic activity towards the lead and cadmium oxidation.
