Book Description
As our knowledge of the mechanism of electrode processes increases, it becomes more and more apparent that the kinetic currents first observed by R. Brdicka and by K. Wiesner in the 1940's are very widely encountered. Very many electrode pro cesses contain a chemical stage. * This is true primarily of elec trode processes that involve organic compounds. Therefore, to understand the mechanism of electrode processes and, particular ly, to correctly interpret the results of polarographic investiga tions, it is important to know the characteristics and relationships controlling the chemical reactions taking place at the electrode surface. Generally, these reactions are substantially different from ordinary chemical reactions taking place in the bulk of the solution, since the reactions at the electrodes are often affected by the electric field of the electrode and the adsorption of the par ticipating compounds . The fact that hydrogen ions usuallY take part in the electro chemical reduction of organic compounds makes possible the use of electrochemical methods, particularly polarography, for the study of protolytic reactions. These reactions play an important role in organic chemistry: the majority of reactions of organic compounds in solutions go through a stage in which a hydrogen ion is removed or added (see, for example, [1, 2]). Therefore, the polarographic study of protolytic reactions can supply much important information to theoretical organic chemistry.

Book Description
Principles of Polarography is a revised and extended version of an original Czech edition that appeared in 1962 at the Publishing House of the Czechoslovak Academy of Sciences in Prague. Based on a one-term course of lectures for third-year students of chemistry at the Charles University it brings the fundamental results of more than forty years' research in the field of polarography. The book contains 22 chapters and opens with a discussion of the principles of polarography. This is followed by separate chapters on polarizable electrodes used in polarography; charging current; influence of the resistance of the electrolyte on polarographic curves; migration and diffusion-controlled currents; and equation of a reversible polarographic wave. Subsequent chapters deal with reversible processes controlled by diffusion of complex ions; reversible reduction of organic substances; deposition of mercury ions; irreversible electrode processes; applications of limiting currents; polarographic curves for the formation of semiquinones and dimers; and catalytic hydrogen currents.

Book Description
Organic Polarographic Analysis deals with the applications of polarography in the analysis of organic compounds. The principles, techniques, and apparatus of organic polarography are discussed, and some selected examples of the applications of organic polarography in various fields of applied chemistry are presented. The direct methods in which the sample is simply dissolved in a suitable supporting electrolyte are also considered. This book consists of 11 chapters and opens with an overview of the basic principles of the polarographic method of analysis, as well as the different types of polarographic limiting currents and of electrode processes. The reader is then introduced to the instruments used in polarography, including the polarograph, dropping and reference electrodes, and electrolysis vessels. Experimental techniques in organic polarography are also described, along with some of its practical applications in fields such as pharmacy, medicine, and biochemistry. Subsequent chapters explore polarographic methods used in the analysis of organic substances, including direct and indirect methods of analysis; separation techniques; and the use of polarography in organic synthesis and isolation of natural products. This monograph is written primarily for organic and analytical chemists.

Book Description
Volumes 26 and 27 are both concerned with reactions occurring at electrodes arising through the passage of current. They provide a comprehensive review of the study of electrode kinetics. The basic ideas and experimental methodology are presented in Volume 26 whilst Volume 27 deals with reactions at particular types of electrodes.Chapter 1 serves as an introduction to both volumes and is a survey of the fundamental principles of electrode kinetics. Chapter 2 deals with mass transport - how material gets to and from an electrode. Chapter 3 provides a review of linear sweep and cyclic voltammetry which constitutes an extensively used experimental technique in the field. Chapter 4 discusses a.c. and pulse methods which are a rich source of electrochemical information. Finally, chapter 5 discusses the use of electrodes in which there is forced convection, the so-called ``hydrodynamic electrodes''.
