A carbon paste electrode (CPE) chemically modified with multiwall carbon nanotubes and
ferrocene (FC) was used as a selective electrochemical sensor for the simultaneous
determination of trace amounts of cysteamine (CA) and folic acid (FA). This modified
electrode showed very efficient electrocatalytic activity for the anodic oxidation of CA. The
peak current of differential pulse voltammograms of CA and FA increased linearly with their
concentration in the ranges of 0.7–200μmol/L CA and 5.0–700μmol/L FA. The detection ...
