Adsorption of Inorganic Phosphorus by River Sediments

Abstract

The adsorption of phosphate by river sediments taken from a small suburban river was investigated. The experimental results indicated that the phosphate adsorption capacity of sediments significantly correlates with the amounts of contained organic substances and is highly controlled by contained Fe and Al. The phosphate adsorption behavior fits Freundlich equation and the Freundlich constant is almost the same for every sediment samples.
