Surface| Резюме: | The oxidation of phenylethylamine and tyramine at the paste electrode of carbon nanotubes by cyclic voltammetry method was studied to determine the concentration of these biogenic amines in aqueous solutions. The carbon nanotubes were prepared by pyrolisis of benzene with nanocrystalline nickel catalyst electrodeposited on the thermoexfoliated graphite particle surface. The efficiency of such electrodes for amperometric determination of investigated biogenic amines in concentration range 1×10-4 – 1×10-2 mol×dm-3 has been shown. It has been found that in spite of presence of hydroxyl groups, which are able to anodic oxidation, only amino groups give electrochemical response. |
