An electrochemical method is described for the voltammetric determination of isoproterenol
in the presence of uric acid using p-chloranil-carbon nanotubes paste electrode. Cyclic
voltammetric, chronoamperometric, and electrochemical impedance spectroscopic methods
have used to investigate the suitability of p-chloranil as a mediator for the electrocatalytic
oxidation of isoproterenol at pH= 10.5. Using differential pulse voltammetry, isoproterenol
(ISPT) and uric acid (UA) in a mixture can be measured simultaneously and individually ...
