Summary

The sorption and desorption of radionuclide ⁹⁰Sr²⁺were investigated on untreated calcareous soil and two treated soils to remove organic matter and calcium carbonate using batch technique. The experiments were carried out at ambient condition, pH 7.8±0.1 and in the presence of 0.001M NaCl. Effects of fulvic acid and ionic strength on the sorption of ⁹⁰Sr²⁺on calcareous soil were also studied. It was found that the sorption isotherms are linear in the strontium concentration range used herein, and the sorption of ⁹⁰Sr²⁺on the calcareous soil can be described as a reversible sorption process and the sorption mechanism is mainly ion-exchange. The sorption is dependent on ionic strength, and fulvic acid enhances the sorption of ⁹⁰Sr²⁺on calcareous soil. Organic matter present in the calcareous soil is a significant trap of ⁹⁰Sr²⁺and is responsible for the sorption.
