The definitive text for water chemistry professionals and students worldwide.
Principles and Applications of Aquatic Chemistry provides a solid foundation for understanding the chemistry of lakes, oceans, rivers, estuaries, and other natural waters. Acclaimed for its user-friendly pedagogy, this classic textbook explains aquatic chemistry through the powerful application of the "tableau system," which provides a systematic way to organize complex chemical equilibrium problems.
Now in its second edition, this title contains an entirely new introductory chapter and new coverage of ocean acidification, advances in dissolution kinetics, bioavailability of trace metals, redox kinetics, and updated thermodynamic data. The use of computer programs to calculate chemical equilibrium in natural waters is illustrated. Throughout this edition, revised and streamlined material is supported by new real-world examples and full-color illustrations.
Accessible to those with diverse backgrounds in the sciences and engineering, this essential textbook
This comprehensive guide remains the perfect textbook for advanced students in chemistry, environmental science and engineering, marine science, geochemistry, oceanography, geology, fisheries, forestry, and environmental policy and management. It is also a valuable reference text for industry professionals, academic researchers, policymakers, and college and university instructors in relevant fields.

Dateiformat: PDFKopierschutz: Adobe-DRM (Digital Rights Management)
Systemvoraussetzungen:
Das Dateiformat PDF zeigt auf jeder Hardware eine Buchseite stets identisch an. Daher ist eine PDF auch für ein komplexes Layout geeignet, wie es bei Lehr- und Fachbüchern verwendet wird (Bilder, Tabellen, Spalten, Fußnoten). Bei kleinen Displays von E-Readern oder Smartphones sind PDF leider eher nervig, weil zu viel Scrollen notwendig ist. Mit Adobe-DRM wird hier ein „harter” Kopierschutz verwendet. Wenn die notwendigen Voraussetzungen nicht vorliegen, können Sie das E-Book leider nicht öffnen. Daher müssen Sie bereits vor dem Download Ihre Lese-Hardware vorbereiten.
Bitte beachten Sie: Wir empfehlen Ihnen unbedingt nach Installation der Lese-Software diese mit Ihrer persönlichen Adobe-ID zu autorisieren!
