In this work, p-aminophenol–multiwall carbon nanotubes–TiO2 is proposed as a sensor for
the rapid, sensitive, and highly selective voltammetric determination of penicillamine (PA) in
the presence of uric acid (UA). The electrochemical behavior of the compounds at this
modified electrode was studied by cyclic voltammetry (CV), differential pulse voltammetry
(DPV), and electrochemical impedance spectroscopy (EIS). The results indicated that the
chemically modified electrode exhibits efficient electrocatalytic activity in the oxidation of ...
