A Thermodynamics-Based Conceptual Model for Colloid-Facilitated Solute Transport

Chapter
Part of the Theory and Applications of Transport in Porous Media book series (TATP, volume 25)

Abstract

As mentioned above (Sect. 19.1.2), changes in the physicochemical conditions in the system over space and time, which take place in unsteady-state migration flows, reduce the potential of the above-considered sorption isotherm-based models with time-invariant coefficients, in particular, models describing colloid-facilitated transport. Their empirical nature does not allow them to be applied outside of the specific parameters of the contaminated site. Therefore, thermodynamics-based approach, describing sorption as a series of specific reactions between dissolved ions and surface sites, can be more productive for analyzing solute transport under field conditions.
