Public ISBD Titre de série : U.S. Geological Survey Water Supply paper, 2286 Titre : Gas-film coefficients for the volatilization of ketones from water Type de document : texte imprimé Auteurs : Rathbun, R. E. ; Tai, D. Y. Mention d'édition : U. S. geological Survey Editeur : U. S. Geological Survey Année de publication : 1986 ISBN/ISSN/EAN : CI-05050 Note générale : Volatilization is a significant process in determining the fate of many organic compounds in treams and rivers. Quantifying this process requires knowledge of the mass-transfer coefficient from water, which is a function of the gas-film and liquid-film coefficients. The gas-film coefficient can be determined by seasuring the flux for the volatilization of pure organic liquids. Ten the report shows that the gas-film coefficient for acetone was much more dependent on temperature than more the coefficient for the other ketones.
