A new vinylferrocene modified-multiwalled carbon nanotubes paste electrode was prepared
and used for the determination of N-acetylcysteine (N-AC) and folic acid (FA). Using the
modified electrode, a highly selective square wave voltammetric method for the
simultaneous determination of N-AC and FA was developed. The peak currents of N-AC and
FA increased linearly with their concentration in the ranges of 0.1–662 and 10.0–900 mmol
Lā1, respectively, with corresponding detection limits of 0.09 and 7.0 mmol Lā1. The RSD ...
