"This book is an excellent treatise on the fundamentals of modern electrochemistry and its applications to the solution of analytical and remedial environmental problems...readable by engineers, chemists, physicists, biologists, and other technical persons trained at the level of advanced undergraduate students and beyond..."
--James F. Rusling, University of Connecticut, JOURNAL OF AMERICAN CHEMICAL SOCIETY

"Explores the application of electrochemical and photochemical methods to pollution sensors and abatement. Intended for both an environmental specialist audience and for the practicing electrochemist, the focus is the positive role that electrochemical science and engineering can play in the detection, quantification, and treatment of environmental pollutants."
"...this book presents some of the most modern approaches to sensing and remediating pollutants, and does in comprehensively..."
