Abstract

Multi walled carbon nanotubes were used for modification of thick-film carbon-containing electrodes for adsorptive stripping voltammetry. A complex compound of Fe(III) with pyrocatechol was chosen as model system. As compared to the electrodes fabricated without using carbon nanotubes, the modified ones have the recovery close to 100%, 2 times higher sensitivity, and 3 times lower limit of detection. The developed sensors can be used for quick determination of trace amounts of iron in real objects.
