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.
Principles of Polarography
Author: Jaroslav HeyrovskýPublisher: Elsevier
ISBN: 1483264785
Category : Science
Languages : en
Pages : 582
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
Even though the nwnber of requests for reprints and the number of quotations in the Science Citation Index has indicated an ever-increasing interest in topics of organic polarography, I have often felt that the reason that some work is less known may well be because the papers were published in less accessible journals. Therefore, I was pleased when I was asked to prepare a selection of my papers on organic polarography for reprinting. This collection of papers may indicate some of the possibilities offered by polarography in the study of properties of organic compounds. The fact that the papers are published in one volume, not only makes the information more easily accessible for the reader, but also enables a direct comparison of related topics. The mode of selection is discussed in the Introduction. The papers reprinted in this volume are mostly based on work carried out in the J. Heyrovsky Institute of Polarography of the Czechoslovak Academy of Sciences in Prague, in cooperation with my co-workers. I would like to take this opportunity of thanking all of them for the pleasure I got from this cooperation on the solution of varying problems of organic electrochemistry .
Organic Polarographic Analysis

ISBN: 1483152278
Category : Science
Languages : en
Pages : 331
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.
Enzyme Kinetics

Pages : 338
Book Description
Now in full color for a more intuitive learning experience, this new edition of the long-selling reference also features a number of new developments in methodology and the application of enzyme kinetics. Starting with a description of ligand binding equilibria, the experienced author goes on to discuss simple and complex enzyme reactions in kinetic terms. Special cases such as membrane-bound and immobilized enzymes are considered, as is the influence of external conditions, such as temperature and pH value. The final part of the book then covers a range of widely used measurement methods and compares their performance and scope of application. With its unique mix of theory and practical advice, this is an invaluable aid for teaching as well as for experimental work.

Languages : en
Pages : 469
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''.

Book Description
Advances in Polarography, Volume 1 is a collection of papers presented at the Second International Congress of Polarography held at Cambridge in 1959 in honor of the 70th birthday of Professor Heyrovsky. This book is composed of 26 chapters and begins with discussions of the principles, mode of operation, and application of several polarographic techniques, including oscillographic, derivative, continuous, and differential cathode-ray polarography. The succeeding section discusses the theoretical, kinetic, and fundamental aspects of these techniques. The remaining sections are devoted to the analytical, industrial, biological, and medical applications of polarography.
