A ferrocenemonocarboxylic acid modified carbon nanotubes paste electrode
(FMAMCNTPE) was constructed and used as a fast and sensitive tool for the determination
of isoproterenol (ISPT) at trace level. It has been shown by direct current cyclic voltammetry,
double step chronoamperometry and electrochemical impedance spectroscopy (EIS) that
this modified electrode can catalyze the oxidation of ISPT in aqueous solution. The kinetic
parameters of the system including electron transfer coefficient, and rate constant for the ...
