Voltammetric Determination of Captopril Using Chlorpromazine as a Homogeneous Mediator
Figure 5
(A) Chronoamperometric responses of a GCE in a phosphate buffer solution (pH 4.0, 0.05 M) + 1.50 mM CPZ and different amounts of CAP: a: 0.0 mM; b: 0.1 mM; c: 0.2 mM; d: 0.3 mM; e: 0.4 mM; f: 0.5 mM. (B) Plots of currents versus the square root of time elapsed () for the chronoamperograms in (A) b to f. (C) Plots of versus square root of time elapsed () for the chronoamperograms in (A) b to f. The step potential was +0.850 V versus SCE.
