A multiwall carbon nanotubes modified electrode was prepared using ferrocenedicarboxylic
acid as a mediator to be used as an amperometric sensor for the simultaneous
determination of 6-thioguanine and folic acid. The electrochemical behaviors of the
compounds at this modified electrode were studied using cyclic voltammetry, differential
pulse voltammetry, and electrochemical impedance spectroscopy. The results indicated that
the chemically modified electrode exhibited an efficient electrocatalytic activity towards the ...
