The power of electrochemical measurements in respect of thermodynamics, kinetics and analysis is widely recognised but the subject can be unpredictable to the novice even if they have a strong physical and chemical background, and most especially if they wish to pursue quantitative measurements. Accordingly, some significant experiments are perhaps wisely never attempted while the literature is sadly replete with flawed attempts at rigorous voltammetry.This textbook considers how to implement designing, explaining and interpreting experiments centred on various forms of voltammetry (cyclic, microelectrode, hydrodynamic, etc.). The reader is assumed to have knowledge of physical chemistry equivalent to Master's level but no exposure to electrochemistry, or voltammetry in particular. While the book is designed to stand alone, references to important research papers are given to provide an introductory entry into the literature.In this fourth edition, important parts of the text have been re-written for optimal clarity, recognising that many readers will not have English as a first language. Updates to the text have been made and new, additional material included, expanding the text whilst retaining the overall concise, to-the-point approach which has proved popular with the readers of the previous editions.
