We examined effects of soil characteristics and phosphate on soil PFOS adsorption. SOM in soils promoted sorption of PFOS; ferric oxides had the opposite effect. Batch sorption data gave nonlinear PFOS adsorption isotherms for each tested soil. In ferric oxide-rich soil, PO4 is a stronger adsorption site competitor than PFOS. In soil with a high SOM content, PO4 is a weaker competitor than PFOS.
