摘　　要：Under the assistant effect of sulfur, carbon nanotubes electrodes were prepared on the end of tungsten strings directly through microwave plasma chemical vapor deposition. And the electrochemical behavior of CuSO4 at the carbon nanotubes electrodes was investigated. Compared to the graphite electrode, carbon nanotubes elec- trodes had better electrochemical behavior for the analysis of Cu2+. Different electrodes prepared under the same condition showed good consistency of electrochemical detection property. And because carbon nanotubes were synthesized directly on the end of tungsten strings, the results of long-term stability experiments demonstrated that the carbon nanotubes electrodes had stable response to Cu2+ solution.Under the assistant effect of sulfur, carbon nanotubes electrodes were prepared on the end of tungsten strings directly through microwave plasma chemical vapor deposition.
