Increased concentrations of organic pollutants in waters can result from the growth of certain industrial activities. In order to develop a fast electrochemical method to quantitatively determine the concentrations of such pollutants, new electrode materials are required. This book focuses on the preparation, characterisation, and electrochemical behaviour of advanced carbon-based composite electrodes (ie: expanded exfoliated graphite-epoxy, carbon nanofibre-expanded graphite-epoxy, expanded graphite-epoxy, and expanded graphite-polystyrene).
