“…In the previous study (Dimović et al 2013), characterization of the sample has revealed that the soil was medium carbonated (5.4 % CaCO 3 ), with a very low content of accessible phosphorous (7.4 mg per 100 g P 2 O 5 ) and medium content of potassium (12 mg per 100 g K 2 O). The quantity of total organic carbon was 2.1 %.…”

“…Sample exhibited weak alkaline reaction with water (8.0) and low cation exchange capacity (13 meq per 100 g). Furthermore, XRD analysis showed that the sample consisted mainly of quartz, kyanite and muscovite, with smaller quantities of mica, albite, kaolinite and calcium, magnesium carbonate (Dimović et al 2013).…”

Sorption-desorption properties of cobalt(II) and strontium(II) ions were studied using a soil sample from the vicinity of the Serbian radioactive waste processing and interim storage facilities. The mobility of the cations in the soil was evaluated and compared with the intention to facilitate the selection of optimal remediation strategy in case of accidental soil contamination with radioactive cobalt-60 and strontium-90 isotopes. A systematic sorption study was performed through a series of batch experiments at different aging times, cation concentrations and pH. Kinetics experiments revealed that sorbed amounts of cobalt(II) continuously increased with contact time until quasi-equilibrium was reached, while initial fast strontium(II) sorption was followed by a desorption step. Based on the shapes of the sorption isotherms and calculated sorption parameters, it was concluded that cobalt(II) sorbed more selectively and strongly than strontium(II). Sequential extraction showed that, regardless of the initial content of contaminants in the soil and the aging time, high amounts of both cations were bonded to relatively mobile fractions: strontium(II) in the exchangeable, while cobalt(II) in the carbonate and ferromanganese oxide fraction. Strontium(II) was readily desorbed in acidic, calcium(II) and ethylenediaminetetraacetic acid-containing media, whereas complexing agents such as citric and tartaric acids at low pH were more effective reagents for cobalt(II) desorption. The results from the present study indicate that chemical extraction can be considered as remediation option for strontium(II)-and cobalt(II)-contaminated soil.
