| Summary: | 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. |
