ABSTRACT
Electroanalytical methods are concerned with the interplay between electricity and chemistry, namely, the measurements of electrical quantities such as current or potential, and their relationship to chemical parameters. Electroanalytical chemistry can play a major role in pollution control and prevention. In particular, electrochemical sensors and detectors are very attractive for on-site and in-situ monitoring of priority pollutants. Such devices are highly sensitive, selective toward electroactive species, fast, accurate, compact, portable, and inexpensive. Several electrochemical devices, such as oxygen or pH electrodes, have been widely used for years for environmental analysis. Recent advances in electrochemical sensor technology have expanded the scope of electrochemical devices toward a wide range of organic and inorganic contaminants.
