Carbon Nanotubes as Electrodes of Electrochemical Sensors



G. V. Zagorovskiy, I. G. Sydorenko, V. V. Lobanov

Abstract


Electrochemical sensors have large perspectives for exploration to presence of toxic compounds in environment determination. It have been shown advantages of paste electrodes of multi-walled carbon nanotubes to mercury (II) and chromium (VI) content in aqueous medium determination. The role of oxygen-containing groups at the nanotubes tips to the metal ions adsorption was discussed. These electrodes allow to determinate Hg (II) content in water at the lowest limit of 20 ng×dm-3 and Cr (VI) in concentration interval of 50–150 mcg×dm-3.
