ANALYSIS AND MODELLING OF SORPTION PROCESSES IN COMPLEX MATERIALS

Abstract

The objective of this document is to explain, in a simple way, the basics of adsorption

processes, including the main experimental methodologies to tackle them, and the principal

methods to analyse and interpret the experimental data.

The concept of electrical double layer and surface complexation models (SCMs), will be

briefly explained. A short description of the methods for determining the SCMs’ parameters

(surface sites, surface charge, acid-base dissociation constants, etc) will be given. The

possible approaches for the application of SCMs to complex systems will be discussed.
