The chapter is an update of one published in 2009, covering the literature up to the autumn of 2014. Due to space limitations assigned to chapters in this book, the review of analytical methods was divided into two parts, the present chapter dealing with electrochemical methods of analysis, especially modified electrodes, and its companion dealing with all the rest. The same guidelines as in the older chapter were followed for the selection of analytical methods, namely: detection and determination of specific metal enolates, conversion of metal cation analytes into complexes with enolic ligands before end analysis and the use of certain metal enolates as analytical aids and tools.

A simple procedure for the simultaneous determination of acetaminophen (AC) and ascorbic acid (AA) by differential pulse voltammetry (DPV) using a carbon nanotube paste electrode exploiting measures in cetylpyridinium bromide (CPB) medium is described. Under the best instrumental parameters of DPV, optimized by means of factorial design, the calibration plots in the range 100.0–700.0 µmol L−1 (r=0.993) and 39.4–146.3 µmol L−1 (r=0.995) with limits of detection of 7.1 and 2.1 µmol L−1, were achieved for AA and AC, respectively. The developed method was successfully applied for the AC and AA determination in pharmaceutical formulations, whose accuracy was attested by comparison with HPLC method.
