Diffusion in Natural Porous Media: Contaminant Transport, Sorption/Desorption and Dissolution Kinetics: Topics in Environmental Fluid Mechanics, cartea 1
Autor Peter Grathwohlen Limba Engleză Paperback – 12 oct 2012
Diffusion in Natural Porous Media: Contaminant Transport, Sorption/Desorption and Dissolution Kinetics compiles methods for calculating the diffusion coefficients of organic compounds (in aqueous solution or vapor phase) in natural porous media. The author uses analytical solutions of Fick's 2nd law and some simple numerical models to model diffusive transport under various initial and boundary conditions. A number of these models may be solved using spreadsheets.
The book examines sorption/desorption rates of organic compounds in various soils and aquifer materials, and also examines the dissolution kinetics of nonaqueous phase liquids in aquifers, in both the trapped residual phase and in pools.
Diffusion in Natural Porous Media: Contaminant Transport, Sorption/Desorption and Dissolution Kinetics concludes with a discussion of the impact of slow diffusion processes on soil and groundwater decontamination and the implications of these processes for groundwater risk assessment.

Recenzii
`... this book forms a very useful reference for data on diffusion parameters and also on methdology for quantifying contaminant transport related to diffusional processes.'
