| 中文摘要 | the electrooxidation of l-dopa at gc electrode was studied by in situ uv-vis spectroelectrochemistry (sec) and cyclic voltammetry. the mechanism of electrooxidation and some reaction parameters were obtained. the results showed that the whole electrooxidation reaction of l-dopa at glassy carbon (gc) electrode was an irreversible electrochemical process followed by a chemical reaction in neutral solution (ec mechanism). the spectroelectrochemical data were treated by the double logarithm method together with nonlinear regression, from which the formal potential e-0 = 228 mv, the apparent electron-transfer number of the electrooxidation reaction an = 0.376 (r = 0.99, sd = 0.26), the standard electrochemical rate constant k(0) (3.93 +/- 0.12) x 10(-)4 cm s(-1) (sd = 1.02 x 10(-2)), and the formation equilibrium constant of the following chemical reaction k(c)= (5.38+/-0.34) x 10(-1) s(-1) (sd = 1.02 x 10(-2)) were also obtained. |
