A novel modified electrode was constructed by intercalating carbon nanotubes to graphite surface that has more advantage than film modified one. The electrochemical behaviors of dopamine (DA) and ascorbic acid (AA) on the modified electrode were investigated with cyclic voltammetry. The carboxylic carbon nanotubes2intercalated electrode not only showed electrocatalytic oxidation of DA and AA but also separated DA from AA. The anodic potential difference of DA and AA was about 160 mV. Moreover , the sensitivity of DA was higher than that of AA. So dopamine can be determined in the presence of plenty of AA. The 1st order derivative of reduction peak current is proportional to DA concentration in the range of 5 ×10 -7 ~1 ×10 -4 molΠ L in the presence of 1 ×10-3 molΠ L AA , and the detection limit can reach 1 ×10-7 molΠ L.
