Abstract
The electroanalytical techniques of pulse polarography, stripping voltammetry and on-line electrochemical detection have been used for the identification and determination of trace concentrations of a wide variety of environmentally significant organic molecules, usually after the application of sample pretreatment procedures, certain separation techniques and, in some cases, derivatisation. Classes of molecules that can be determined using these methodologies are carbonyls, simple aromatics such as nitroaromatics, phenols, polychlorinated aromatics, carboxylic acids, sulphonates, organophosphorus compounds, azomethines, thiols, carbamates and amines.
