Phosphorus adsorption by kaolinite and montmorillonite: I. Effect of time, ionic strength, and pH

The objective of this work was to study specific effects of total P concentration, pH, ionic strength, and equilibration time on P partitioning between solid and solution phases of Ca- and K-kaolinite and -montmorillonite suspensions as model systems of soils containing these minerals. Phosphorus concentration in the solution phase (C p ) stabilized within 24 to 48 h after introducing P into the system
