Sorption behavior of uranium in agricultural soils

Abstract

Because mineral phosphorous fertilizers are often loaded with uranium (U), their application could cause a significant U contamination of agricultural soils. In order to predict the mobility and plant availability of U, it is necessary to describe the liquid/solid distribution of U in soils. First results indicate a high adsorption of U onto the soil matrix. Freundlich adsorption coefficients (log Kf) range between 1.3–6.7 and illustrate the different sorption capacity of the investigated soils.
