Lab Memo: Cyclic Voltammetry: Identification and Quantification of Unknown Concentrations of Substituted Benzoquinones
Cyclic Voltammetry (CV) measures the redox behavior of electeroactive species and is useful for a whole spectrum of molecules in inorganic chemistry, biochemistry, electrochemisty as well as organic chemistry. A voltammogram is the readout of the energy scan which can be used to determine unknown concentrations. Voltammogram wave shape is very different than in spectrometry and chromatography. The wave is triangular in shape because the y-axis describes the shift in the potential which is the voltage of a working electrode versus a reference electrode. The x axis describes duration in seconds. (Kissinger and Heineman).
Two samples each with an unknown concentration of benzoquinones were analyzed with the instrument, BASi Epsilon-EC.
