Basic Microscopic Theory of the Distribution, Transfer and Uptake Kinetics of Dissolved Radionuclides by Suspended Particulate Matter-Part I: Theory Development

摘要

Recently much experimental effort has been focused n determining those factors which affect the kinetics and the final equalibrium conditions for the uptake of radionculides from the aqueous phase by particulate matter. At present, some of these results appear to be either surprising or contradictory and introduce some uncertainty in which parameter values are most appropri- ate for environmental modelling. In this paper, we study the ionic exchange between the dissolved phase and suspended particles from a microscopic viewpoint, developing a mathematical description of the kinetic transfer and the k_d distribution coefficients.
