Conteúdo:

Reversible equilibrium adsorption-desorption relationships were inadequate for describing
the transport of orthophosphate through water-saturated and water-unsaturated cores
from surface A1, and subsurface A2 horizons of Oldsmar fine sand. Using a kinetic model
with nonlinear reversible adsorption, desorption improved descriptions of phosphorus
through these soils. Phosphorus effluent concentrations were described best by using an irreversible sink for chemical immobilization or precipitation with a nonlinear reversible kine-
tic adsorption-desorption equation.
