چکیده:

The electrochemical activity of fore different carbon nanotube modified graphite electrodes, treated and functionalized with three methods has been assessed and compared. These treatment attaches COOH groups to the multi-walled carbon nanotube (MWCNT). The amperometric thiocholine detection on MWCNT modified electrode at +750 mV provided at least 20% increase in sensitivity and 10% in range of linearity compares with bare electrode.
