Application of Chemical Speciation Modelling to Studies on Toxic Element Behaviour in Soils

Modeling the adsorption of Cd (II), Cu (II), Ni (II), Pb (II) and Zn (II) onto montmorillonite

“…However, in the past two decades, surface complexation models (SCM's) have been increasingly used to describe the adsorption behavior of cations and anions onto oxide minerals and phyllosilicate clay minerals (Dzombak and Morel, 1990;Davis and Kent, 1990;Goldberg, 1992;Evans et al, 2010). These more mechanistic models provide the opportunity to study the adsorption affinity of ions based on their thermodynamic binding constants.…”
