Zusatztext The text is a very useful reference source to current methods! and highlights directions where improvements in nanotechnology will allow production of smaller! more sensitive instrumentation. Although many of the techniques are familiar to most electroanalytical chemists! many chapters detail interesting developments in their use. Klappentext This book examines the usefulness of electrochemical methods for understanding complex natural biogeochemical processes. It describes techniques developed to measure trace metals, redox species, and major ions in fresh- and marine waters, hydrothermal vents, sediments, microbial mats, extraterrestrial systems, and at mineral-water interfaces. It will be of use to scientists and researchers who need to describe biogeochemical cycling of trace elements in natural environments.
