摘　　要：The electrochemical behavior of the film of single wall carbon nanotube(SWNT) functionalized with carboxylic acid group was studied extensively at the glassy carbon(GC) electrode. One stable couple of waves corresponding to the redox of the carboxylic acid group, which was supported by the IR experiments, was observed. The electrode process involved four electrons, while the rate determining step was a one-electron reduction. The SWNT film modified electrode showed nice electrocatalytic behaviors toward the oxidations of some biomolecules such as dopamine, epinephrine and ascorbic acid.
