Diffusive Gradients in Thin-Films for Environmental Measurements

Description

The diffusive gradients in thin-films (DGT) technique is a means of measuring the concentration and speciation of metals in natural waters. Edited by one of the pioneers of the technique, this unique volume provides a complete and authoritative guide to the theory and applications of DGT. The book includes explanations of the fundamental principles of DGT, accessible to readers with a modest background in chemistry, as well as more advanced chapters that provide a thorough treatment of the physical and chemical dynamics of this technique and evaluate how well it mimics the biological uptake process. Chapters on natural waters, soils and sediments illustrate the applications of DGT, and detailed instructions are included on how to use DGT in practice. Combining the fundamentals of DGT with more advanced principles, this is an indispensable text for students, researchers and professional scientists interested in the chemistry of natural waters, soils and sediments.

William Davison is Emeritus Professor of Environmental Chemistry at Lancaster Environment Centre, Lancaster University, UK, where he has previously served as Head of Department. His studies, complemented by research in environmental analytical chemistry, focus on the biogeochemistry of carbon, iron, manganese, sulphur and trace metals in natural waters. Professor Davison, with his colleague Hao Zhang, developed the techniques of diffusive equilibration in thin-films (DET) and diffusive gradients in thin-films (DGT) and pioneered their initial applications in waters, soils and sediments. He has contributed to over 250 publications, and the applications of his work have been recognised by the Pollution Abatement Technology Awards and the RSC Sustainable Water Award.

'For the first time, a complete single information source is available that covers the whole DGT concept, covering both the principal mechanisms and the whole range of application possibilities. Everyone who is interested in starting or continuing DGT work will find a comprehensive and detailed compilation of the current DGT knowledge. The publication of this book is a milestone in agricultural and environmental chemistry and will further boost the application of DGT and the further development of DGT application approaches.'
