Investigation on the thermal stability of cesium in soil pretreatment and its separation using AMP-PAN resin

Cesium-137 ( 137 Cs) is a main product of the nuclear fission. The release of 137 Cs can contaminate soil by deposition from the atmosphere. It is critical to develop a high-efficiency way to determinate 137 Cs in the soil. To reach it, the sample pretreatment and 137 Cs separation from sample matri...

Zusammenfassung:	Cesium-137 ( 137 Cs) is a main product of the nuclear fission. The release of 137 Cs can contaminate soil by deposition from the atmosphere. It is critical to develop a high-efficiency way to determinate 137 Cs in the soil. To reach it, the sample pretreatment and 137 Cs separation from sample matrix is significant. This work focused on the thermal stability of Cs(I) during soil dry ashing and acid solution evaporation. The separation performance of AMP-PAN resin for Cs(I) was investigated through batch and dynamic column experiments. The results reveal that Cs(I) does not loss during soil sample dry ashing (T
