Summary
The sorption of aqueous species onto solid surfaces exerts an important control on the mobility and bioavailability of dissolved mass in the natural environment. This chapter shows how sorption reactions can be incorporated into multicomponent speciation models using distribution coefficients, Freundlich isotherms, Langmuir isotherms, and ion exchange theory.
