Abstract: A novel modified electrode was prepared by electrochemicaly cycling scanning the glass carbon electrode covered with a macroporous alumina membrane in a solution containing PPy and PMo 12O3- 40. The reversibility of the cyclic voltammograms was improved obviously. The remarkable advantage of the modified electrode wasthe high sensitivity and favorable electrocatalytic behavior toward NO2-. The peak current increased linearly with the concentration of NO2- in the range of 8.0×10-7—0.01 mol/L. The detection limit of NO2- was 1.0×10-9mol/L. The polyoxometalates nanopaticles modified electrode exhibited almost the same electrochemical behavior after 7 d. It is indicated that the PMo12-PPy/AGCE has a good reproducibility, stability and wide linearity range.

Key words: Polyoxometalates nanopaticles, Anodic aluminum oxide films, Modified electrode, NO2-
