Application of Multi-Walled Carbon Nanotubes Modified Glassy Carbon Electrode for Determination of Mefenamic Acid in Pharmaceutical Preparations and Biological Fluids

Summary: A chemically modified electrode is constructed based on multi-walled carbon nanotube modified glassy carbon electrode (MWCNTs/GCE). It is demonstrated that this sensor could be used for determination of pharmaceutically important compound mefenamic acid (MEF). Differential pulse voltammetry (DPV) experiments of various concentration of MEF showed two linear dynamic ranges. The first linear dynamic range was from 2 µM to 40 µM, and the...
