Textbook in PDF format This textbook provides both an easy introduction to all topics related to modern electrochemistry in addition to inclusive synopsis of the subject. Electrochemistry is the study of chemical processes that cause electrons to move. For decades electrochemical technology has contributed successfully to environmental protection. In addition, environmental electrochemistry is capable of giving a huge contribution to further reach this goal by application and improvement of existing technology, and research, development and implementation of new technology. Electrochemical engineering became a science branch which at first developed with little reference to chemical engineering treating the relevant topics on a high mathematical level. This has led to a certain perfection, which today allows us to model almost any desired electrolyzer or cell configuration with numerical methods to a degree and precision which satisfies the highest demands. In this book, electrochemical processes relevant to this purpose are considered and examples of industrial applications are discussed.
