Electroanalytical Chemistry

"Provide comprehensive, authoritative reviews on recent developments and applications of well-established techniques in field of modern electro-and electroanalytical chemistry, defined in its broadest sense. "

This volume provides a practical, intuitive approach to electroanalytical chemistry, presenting fundamental concepts and experimental techniques without the use of technical jargon or unnecessarily extensive mathematics. This edition offers new material on ways of preparing and using microelectrodes, the processes that govern the voltammetric behavior of microelectrodes, methods for characterizing chemically modified electrodes, electrochemical studies at reduced temperatures, and more. The authors cover such topics as analog instrumentation, overcoming solution resistance with stability and grace in potentiostatic circuits, conductivity and conductometry, electrochemical cells, carbon electrodes, film electrodes, microelectrodes, chemically modified electrodes, mercury electrodes, and solvents and supporting electrolytes.

This thoroughly updated open learning text provides an introduction to electroanalytical chemistry, one of today's fastest growing and most exciting frontiers of analytical science. The author discusses electroanalysis in a non-mathematical and informal tutorial style and offers over 250 discussion and self-assessment questions. In addition he includes 50 worked examples that provide excellent material for testing the reader's understanding of the subject matter. The topics covered include the following: * Simple emf measurements with cells * Equilibrium and dynamic measurements * Polarography * Cyclic voltammetry * Rotated disc, ring-disc and wall-jet electrodes * In situ spectroelectrochemistry measurements * Impedance analysis * Preparation of electrodes * Data processing The book also contains a comprehensive bibliography and details of web-based resources. It assumes no prior knowledge of this powerful branch of analytical science and will be an invaluable aid for anyone wanting to perform analytical measurements using electrochemical technqiues. Is approach makes it also ideal for students.

Provides comprehensive, authoritative reviews on recent developments and applications of well-established techniques in the field of modern electro- and electroanalytical chemistry, defined in its broadest sense.

This book examines the metal/solution interface with the electrochemical quartz crystal microbalance, exploring electrostatic adsorption, metal deposition, and roughness. It explores the indirect laser-induced temperature-jump method for characterizing fast interfacial electron transfer.

For more than three decades the Electroanalytical Chemistry series has delivered the most in-depth and critical research related to issues in electrochemistry. Volume 22 continues this gold-standard with practical reviews of recent applications, as well as innovative contributions from internationally respected specialists highlighti

Provides a strong foundation in electrochemical principles and best practices Written for undergraduate majors in chemistry and chemical engineering, this book teaches the basic principles of electroanalytical chemistry and illustrates best practices through the use of case studies of organic reactions and catalysis using voltammetric methods and of the measurement of clinical and environmental analytes by potentiometric techniques. It provides insight beyond the field of analysis as students address problems arising in many areas of science and technology. The book also emphasizes electrochemical phenomena and conceptual models to help readers understand the influence of experimental conditions and the interpretation of results for common potentiometric and voltammetric methods. Electroanalytical Chemistry: Principles, Best Practices, and Case Studies begins by introducing some basic concepts in electrical phenomena. It then moves on to a chapter that examines the potentiometry of oxidation-reduction processes, followed by another on the potentiometry of ion selective electrodes. Other sections look at: applications of ion selective electrodes; controlled potential methods; case studies in controlled potential methods; and instrumentation. The book also features several appendixes covering: Ionic Strength, Activity and Activity Coefficients; The Nicolsky-Eisenman Equation; The Henderson Equation for Liquid Junction Potentials; Selected Standard Electrode Potentials; and The Nernst Equation Derivation. Introduces the principles of modern electrochemical sensors and instrumental chemical analysis using potentiometric and voltammetric methods Develops conceptual models underlying electrochemical phenomena and useful equations Illustrates best practice with short case studies of organic reaction mechanisms using voltammetry and quantitative analysis with ion selective electrodes Offers instructors the opportunity to select focus areas and tailor the book to their course by providing a collection of shorter texts, each dedicated to a single field Intended as one of a series of modules for teaching undergraduate courses in instrumental chemical analysis Electroanalytical Chemistry: Principles, Best Practices, and Case Studies is an ideal textbook for undergraduate majors in chemistry and chemical engineering taking instrumental analysis courses. It would also benefit professional chemists who need an introduction to potentiometry or voltammetry.

This volume is ba. sed on the presentations gi ven at the ElectroFinnAnalysis conference held on J une 6-9, 1988 in Turku-Äbo, Finland. This event was the second in a series of electroanalytical conferences. The first was held in Ireland 1986 and the next will be held in Spain 1990. The aim of these conferences is tobring tagether scientists who use electroanalytical methods in their research. This is also reflected in the disposition of this volume where instrumentation and applications from the different fields have their own chapters. The editors are grateful to Mr. Johan Nyman, Mr. Kent Westerbolm and Mr. Markku Lehto for their technical assistance during the editorial work of this volume.
