A Sensor for Determination of Tramadol in Pharmaceutical Preparations and Biological Fluids Based on Multi-Walled Carbon Nanotubes-Modified Glassy Carbon Electrode

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 pharmaceutical important compound tramadol (TRA). The measurements were carried out using differential pulse voltammetry (DPV), cyclic voltammetry (CV) and chronoamperometry (CA) methods. DPV experiments of various concentration of TRA...
