Abstract The ability of a soil to remove wastewater phosphorus from solutions passing through the soil matrix is primarily related to the formation of relatively insoluble phosphate compounds of iron, aluminum, and calcium. Based on the solubility of these compounds, an estimate can be made of the minimum concentration of phosphorus which will be found at equilibrium in the soil solution. The kinetics of orthophosphorus sorption with 25 viable mineral soils were experimentally measured under laboratory conditions. Several kinetic models were evaluated as a means of describing phosphorus sorption by soil. A diffusion limited Langmuir sorption model best fit the experimental data.
