Abstract: This paper deals with electrocatalytic oxidation of plant hormone 6-benzyl adenine by Cu2+ in BR buffer on GC. It was found that Cu2+ was reduced and generated Cu+, which reacted with 6-benzyl adenine. The 6-benzyl adenine-Cu+ compound reoxidated of Cu+ to Cu2+ and gave an oxidation peak at 0.46 V( vs. SCE). This peak current shows a linear relationship with the concentration of 6-benzyl adenine in the range of 1×10-5～9×10-5 mol/L. When accumulation time was 8 min, a detection limit of 2×10-7 mol/L was obtained.

Key words: Copper ion, 6-Benzyl adenine, Electrocatalytic oxidation
