ELECTROCHEMISTRY FOR A CLEANER ENVIRONMENT

This article reviews electrochemical processes and devices that can co ntribute to a cleaner environment, Electrochemical processes for treat ment of waste water solutions, flue gases and contaminated groundwater and soil are described, as well as improvements of existing electroch emical processes or products in order to minimize their environmental impact. Electrochemical power sources for cleaner generation of electr icity in fuel cell power stations and for electrically driven vehicles are also discussed, Finally, the important role of electrochemical se nsors for monitoring toxic substances is stressed.
