Contemporary Electroanalytical Chemistry

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.

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.

ANALYTICAL ELECTROCHEMISTRY An accessible and robust text with comprehensive coverage of modern electroanalytical techniques and devices In the newly revised 4th edition of Analytical Electrochemistry, distinguished researcher Dr. Joseph Wang delivers an authoritative and comprehensive discussion of modern electroanalytical techniques and devices. With a strong focus on electroanalysis (as opposed to physical electrochemistry), the book offers readers a thorough grounding in the fundamentals of electrode reactions and the principles of electrochemical methods. It also demonstrates the solving of real-life analytical problems using the techniques discussed within. This latest edition contains extensive updates to the cited literature and its descriptions of various electrochemical processes and techniques. Additional worked examples are included in the text and numerous quantitative questions and exercise problems are found at the end of each chapter. Readers will also find: A thorough introduction to the fundamental concepts of electroanalysis, including discussions of Faradaic processes, electrical double layers, and the electrocapillary effect Comprehensive explorations of the study of electrode reactions, interfacial properties, and controlled potential techniques Practical discussions of the practical considerations of electroanalysis, including electrochemical cells, solvents and supporting electrolytes, and instrumentation Detailed treatments of potentiometry and electrochemical sensors, including ion selective electrodes, electrochemical biosensors and wearable devices Perfect for graduate students studying electroanalytical chemistry, Analytical Electrochemistry will also benefit advanced undergraduate students taking courses in instrumental analysis, as well as academics and industrial professionals considering the use of electroanalysis in their labs.
