Introduction to Environmental Analysis - Reeve, Roger N

. .

Résumé :
Welche analytischen Verfahren wendet man zur Charakterisierung von Umweltproben an? Antwort auf diese Frage gibt Ihnen der Autor dieses Bandes. Ausf?hrlich erl?utert er die umweltspezifischen Einsatzgebiete von Gas- und Fl?ssigkeitschromatographie, IR-Spektroskopie und R?ntgenfluoreszenz bei der Boden-, Wasser- und Luftanalyse sowie beim Monitoring bestimmter Schadstoffe. Mit aktuellsten Informationen zu Strategien der Probennahme und zur Extraktion in fester und fl?ssiger Phase!...
