Polymeric toluidine blue and carbon nanotubes and four kinds of modified electrodes were prepared. The electrochemical behavior of VB6 at modified electrodes were studied with cyclic vohammetry. The results indicated that the polymeric' toluidine blue/multi-walled carbon nanotubes modified electrode showed excellent electrochemical activities towards VB6,peak potential shifted negatively 45 mV,the peak current is 2 times higher than the bare glass electrode, the oxidation of VB6 on PTB/MWNT/GC was irreversible and mainly controlled by diffusion. The electron transfer number was 1, proton transfer number was 1, the effective area of electrode was 0. 0409 cm^2, diffusion eoeffcient was 6. 3433 × 10^-4 cm^2/s. A good linearity relationship between peak current and concentration in the range of 8.0 × 10^-6 - 4. 0 × 10^-4mol/L was found, of which the equation was ip (A) = - 1. 9865 × 10^-6 - 0. 1052c(mol/L) , the correlative coefficient R = -0. 9968, and detection limit was 2.0 × 10^-6mol/L. The sample recovery was between 92.63% and 101.50%
