    About this ebook

    About Book

    Analytical methods that are portable, reasonably priced, and use simple instruments have been made possible by electrochemistry. Investigations and monitoring of biological samples, industrial products, and the environment also frequently employ electroanalytical procedures with a high degree of accuracy, precision, sensitivity, and selectivity.

    This book describes the detailed electrochemical terms and concepts engaged in the electrochemical reactions at the electrodes in electrochemical cells. Various types of electrode processes to display the electrochemical main features are concentrated. The basic electroanalytical cell systems and their practical electroanalysis are discussed simply. The book provides readers with a thorough grounding in the fundamentals of electrode reactions and the principles of electrochemical methods. The application of electroanalytical methods to chemical systems is the main prominence while the basic principles of electrochemistry are also discussed.

    Moreover, I am pretty sure that this book will improve the confidence of young researchers and students to think and remember electroanalytical concepts.

    I highly believe that this book will go a long way to satisfy the long-felt need of young researchers/students for a friendly guide on electrochemical analysis and sensors.

    Thank you,

    Dr. Govindhan Maduraiveeran

      Current Analytical Electrochemistry - Maduraiveeran Govindhan

      1  Introduction

      Electrochemistry is a vast and important area of chemistry. The chemical changes caused by the passage of electricity and the production of electrical energy by chemical reactions are the heart of electrochemistry.

      The general event for the electrochemical processes is that of electron transfer between chemical species; or between an electrode and a chemical species situated in the vicinity of the electrode, usually a pure metal or an alloy.

      However, it is very difficult to define accurately the limits of the electrochemistry field and its importance in a variety of areas in chemistry, physics, and biology.

      It is well known universally as fundamental to chemistry, originated in electrochemistry, and is now recognized in various fields, including medicine and the environment, as well as devices such as electrochromic displays, electroanalytical sensors, batteries, and fuel.

      These are dependent in no small way upon the exploitation of electrochemical principles.

      In short, electrochemistry has made chemistry important contributions and the important place that the subject occupies in science and technology at present.  

      Analytical electrochemistry is the application of electrochemical processes on the systems to measure the quantity of a species of interest and it is mainly concerned with the measurements of electrical quantities of current, potential, charge, and chemical parameters.

      For a variety of reasons, including the kinetics of electrochemical reactions, to generate unstable intermediates and detection of trace amounts of chemically/biologically important and toxic molecules and metal ions, electroanalytical researchers make electrochemical measurements on the chemical systems.

      The analytical electrochemical methods are employed in the study of chemical systems and the investigations in which the electrochemical properties of the systems themselves are of primary interest.

      At present many electroanalytical methods have been devised and the specific application needs a better understanding of the principles of electrode reactions and the electrical properties of electrode-solution interfaces.

      Analytical electrochemistry has found a wide range of applications in environmental and food monitoring, and biomedical analysis using electrical measurements. Analytical electrochemistry is fascinating and it is lengthened to new phases of environment and medicine by the design of tailored electrochemical interfaces, molecular monolayer structures, the coupling of electrochemical transducers and chemical/biological components, and the development of analytical techniques.

      The detailed electrochemical terms and concepts engaged in the electrochemical reactions at the electrodes in the electrochemical cell are introduced in this book. I will consider the various types of electrode processes to display the main features.

      Moreover, the basic electroanalytical cell systems and their practical electroanalysis will be discussed simply. Moreover, the application of electroanalytical methods to chemical systems is the main prominence while the basic principles of electrochemistry are discussed.

      2  Fundamental Electrochemistry

      Nicholson and Faraday were initially discovered the electrical decomposition of aqueous solution. Galvani and Volta were observed on the chemical effects of electricity and the electrochemical generation of electricity.

      These findings laid the foundation of concepts regarding the electrical nature of matter and the nature of electrical phenomena.

      Faraday, Berthelot, and Daniell and later Arrhenius Kohlrausch's studies provided a base for the modern concepts of current flow and the conduction in the electrolyte solutions, as well as increasing the understanding of the nature of the processes occurring at the electrode interfaces.
