With a Ni/GC ion implantation modified electrode as working electrode, in 0. 1 mol/L HOAc-NaOAc (pH=4.62) solution, a sensitive reductive wave of ADM was obtained by linear sweep voltammetry. The peak potential was -0.55 V (vs.SCE). The peak current is proportional to the concentration of ADM with a detection limit of 6.9 X 10-8 mol/L. The behavior of the reduction wave was studied. The experiments of AES and XPS showed that Ni was surely implanted into the surface of the GCE and the implanted Ni at the GCE improved the electrocatalytic activity.
