Autor: Sidarta A. Lima, Marcio A. Murad, Christian Moyne, Didier Stemmelen

Publikováno v: Anais da Academia Brasileira de Ciências, Vol 82, Iss 1, Pp 223-242 (2010)

A new three-scale model to describe the coupling between pH-dependent flows and transient ion transport, including adsorption phenomena in kaolinite clays, is proposed. The kaolinite is characterized by three separate nano/micro and macroscopic lengt
