Modeling Dynamic Sorption of Cadmium in Cropland Soils

In sorption experiments, Cd in the solution phase may be surface adsorbed or immobilized and precipitated into mineral phases. The reaction kinetics can be described by a two‐site model combining a linear instantaneous model for the surface adsorption and a first‐order reaction kinetic model with forward and backward reaction constants for the immobilization and precipitation of the mineral phase. A simplified sequential procedure was developed...
