Abstract Objective Radioactive cesium (Cs) was a mian cause of soil radioactive contamination. This study aimed at exploring the effect of montmorillonite on the transfer of cesium in soil-soybean system to provide theoretical basis for the remediation and evaluate bioavailability. Methods Varied montmorillonite were added to the Cs contaminated soil and pot experiments were conducted on soybean[Glycine max (L.) Merr.] uptake Cs in a green house. The bioavailability of Cs in roots directly contact soil, rhizosphere soil and non rhizosphere soil were analyzed with three different extractants. Results Adding 0.5% montmorillonite could significantly decrease Cs transportation, and the concentration ratio (CR) of roots, stems and leaves were 51%、76% and 66% respectively. The content of extracted Cs was in the order:NH₄OAc > HAc > MgCl₂. The exchangeable content extracted by NH₄OAc was 10 times of the other two. There were positive correlation between exchangeable phrase Cs content by HAc and the Cs content in soybean organs. Conclusion By comparison analysis, 0.5% montmorillonite in experiment soil can be used as an optimal choice for soil remediation of Cs pollution. Meanwhile, HAc can be used as a reference to evaluate the bioavailability of Cs in soil.
