Models are available for simulations of proton dissociation and cation binding by natural organic matter; two examples are the NICA-Donnan and Stockholm Humic (SHM) models. To model proton and metal binding, it is necessary to properly account for the ionic strength dependence of proton dissociation. In previous applications of the models for soils itwas assumed that the electrostatic interactions for solid-phase humic substances were the same as in solution; this assumption was recently… CONTINUE READING
