Environmental applications of nanoscale and microscale reactive metal particles (2009)

Public ISBD Titre : Environmental applications of nanoscale and microscale reactive metal particles Type de document : texte imprimé Auteurs : Jonathan G. Geiger, Éditeur scientifique ; Kathleen M. Carvalho-Knighton, Éditeur scientifique Editeur : Washington : American Chemical Society Année de publication : 2009 Collection : ACS symposium series num. 1027 Importance : X, 306 p. Présentation : ill. Format : 24 cm ISBN/ISSN/EAN : 978-0-8412-6992-7 Langues : Anglais (eng) Mots-clés : Métaux lourds -- Aspect environnemental -- Congrès Nanoparticules -- Aspect environnemental -- Congrès Chimie de l'environnement -- Congrès Heavy metals -- Environmental aspects -- Congresses Nanoparticles -- Environmental aspects -- Congresses Environmental chemistry -- Congresses Index. décimale : 504.5 Dommages causés par des matériaux nocifs. Pollutions. Polluants organiques. Substances persistantes, toxiques, bioaccumulatives Résumé : Environmental Applications of Nanoscale and Microscale Reactive Metal Particles takes the reader from current laboratory studies in the function and use of these particles through scale-up and finally to the state-of-the-science in field-scale demonstrations and applications. The book focuses on a variety of environmentally problematic species from metals to halogenated organic compounds and how researchers are developing methods to degrade or sequester these species for the benefit of public health and to help ensure sustainability of precious natural resources. While nanoscale particles, especially iron particles, have been studied extensively for their potential to degrade a variety of organic compounds, microscale systems are of great importance in field application due to financial considerations and actual efficiency in the environment. In addition, other metals, including magnesium and zinc, have great potential for use in the environment in a cost-effective manner.
