| Abstract: | A novel electrode was prepared by self-assembly method in which gold nanoparticles were assembled on the surface of chemically modified ITO conductive glass. UV-vis and cyclic voltammetry were employed to study it. The results showed that electrode exhibited good electrochemical catalytic activity on oxidation of AA. The anodic peak current increased linearly with the concentration of AA in the range from 1.0×10^-5mol .4×10^-2 mol/L with the detection limit of 4.0×10^-6 mol/L. |
