The Theory of Quasi-Steady-State Reversible Wave for Derivative and Semi-derivative Voltammetry at Ultramicro-disk Electrode

本文提出了超微盘电极上准稳态可逆波导数和半导数伏安法理论,对电流、电位的性质进行了详细的讨论.

The theory of quasi-steady-state reversible wave for derivative and semi-derivative voltammetry is described. The behaviour of current-potential curves are discussed in detail. The equations of ia, ia',ia'',ia''' and ea,ea',ea'', ea''' are as follows respectively.(Pa.),fR (P) = 0. 34exp(-0. 66Pa) + 0. 66-0. 13exp(-11/Pa)+0. 351Pa, Pa= (nFrov/ RTDR)1/2, r0 is the radius of electrode, DR is the diffusion coefficient, (ia)?is the maximum current , Em/2a is the half-maximum potential of the anodic wave, v is the sweep rate, CR is the bulk concentration of R.
