Abstract
Experimental data are presented which show that exchangeable aluminum on resin precipitates phosphate from solutions. The precipitation data, however, conform to the Langmuir's and Freundlich's adsorption isotherms. The limitations of these adsorption isotherms in verifying an adsorption reaction are discussed. It is concluded that close agreement between the phosphate fixation data and the two isotherms may not necessarily imply an adsorption reaction in soils.
