Full Description
This book is devoted to the quantitative electrochemical methods of analysis in solution. A theoretical knowledge of each method is discussed. The methods are illustrated with several examples covering a wide range of types of analysis. The book is divided in three parts. The first one is introductory. It recalls some definitions and some basic concepts of electrochemistry. The second part describes the methods themselves. Are studied voltametric methods, amperometry, potentiometry, conductometry, the electrogravimetry and coulometry. Some chapters are also dedicated to the chemical and electrochemical sensors. The third part consists in a supplementary theoretical knowledge of each method.
