【 摘 要 】

Herein, insoluble single-walled carbon nanotube (SWNT) was successfully dispersed into water in the presence of a special kind of surfactant-dicetyl phosphate (DCP), subsequently, a SWNT-DCP composite film coated glassy carbon electrode (GCE) was fabricated. The electrochemical behaviors of 6-benzylaminopurine (6-BAP) at the unmodified GCE and SWNT-DCP modified GCE were examined. It is found that the SWNT-DCP modified GCE remarkably enhances the oxidation peak current of 6-BAP, indicating great potential in the determination of trace level of 6-BAP. Finally, a sensitive and simple voltammetric method with a good linear relationship in the range of 5.0 �? 10^-8~2.5 �? 10^-6 mol/L, was developed for the determination of 6-BAP. The detection limit is as low as 2.0 �? 10^-8 mol/L for 3-min accumulation. This newly-proposed method was successfully demonstrated with practical samples.
