The adsorption of phosphate on particulate matter from the Illinois and Spoon Rivers was investigated. Adsoprtion reached equilibrium after 5 to 6 days and adsorption isotherms were linear for both constant and varying amounts of particulate matter. Adsorption was maximum at pH 8.3 – 8.4 and minimum at 6.0. Rates of adsorption were influenced by the equilibrium concentration of phosphate‐P and were essentially the same for the Illinois and Spoon Rivers. However, the quantity of phosphate‐P adsorbed per unit weight of particulate matter differed for the two streams with that in the Illinois River exhibiting an adsorption capacity 7 times that of the Spoon River.
