A new sensitive voltammetric sensor was developed for electrochemical
determination of captopril (CAP) at a modified multiwall carbon nanotubes paste electrode
with p-aminophenol (p-APMCNTPE). The result showed that p-APMCNTPE has high
electrocatalytic activity for captopril oxidation at pH 6.0. Cyclic voltammetry (CV), double
potential-step chronoamperometry and square wave voltammetric (SWV) were used to
investigate the suitability of p-aminophenol into carbon nanotubes paste matrix as ..
