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.

Binary metal oxides with different degrees of covalent/ionic character of the oxygen-metal bond are tested as a partial coating of glassy carbon electrode surfaces. The electrocatalytic and antifouling properties of the resulting bicomponent electrode systems are analysed in view of possible applications in different fields of electrochemistry, such as electroremediation and electroanalysis. Based on the performance with respect to oxidation of ascorbic acid, as to sensitivity, repeatability of the responses, and activation of electrocatalytic oxidation, CeO2 has been preferred. This same electrode system has been further studied in respect to a trickier electrochemical process, namely the anodic oxidation of a chlorophenol derivative, which induces massive passivation of bare electrode surfaces. The effectiveness of the bicomponent electrode system in anodic oxidation of 2,4,6-trichlorophenol has been ascertained, over a wide range of concentrations, by comparison with pure glassy carbon surfaces
