Abstract

Abstract: The steady-state diffusion current equations of single-sweep, the first differential, the second differential and the third differential voltammetry on microdisc electrode were studied.These currents are directly proportional to r, C, D.The single-sweep limit current is independent of the sweep rate (v), and the first, second and third differential peak current are proportional to v, v², v³, respectively.These results are verified experimental with carbon fiber microdisc electrode.

Key words: Microdisc electrode, Carbon fiber microelectrode, Steady-state voltammetry, Linear sweep voltammetry, Derivative voltammetry
