Abstract
Determination of tryptophan was performed by using of an easy to prepared electrode. Basically, the electrode was prepared by using of ionic liquid and multi-walled carbon nanotube as main constituents. Then, the electrode surface was activated by cycling the potential. The activated multi-walled ionic liquid electrode shows facile electro-oxidation and good stability for determination of tryptophan. Linear range and limit of detection were obtained as 5 × 10–6 to 1 × 10–3 and 2.3 × 10–6 M, respectively. Finally, determination of tryptophan in real samples (commercial amino acid injection and blood serum) was performed successfully. The high activity of the proposed electrode is attributed to the simultaneous presence of ionic liquid and multi-walled carbon nanotube in the electrode content.
