Abstract

The results of cesium recovery from seawater with commercially available Termoxid sorbents (Termoxid 35, Termoxid 3A) under laboratory and expeditionary conditions are presented. The dynamic exchange capacity and the total dynamic exchange capacity of the sorbents for cesium were determined. The breakthrough curves of cesium sorption were plotted for different seawater flow rates, and the physicochemical relationships (isotherm and kinetics) of sorption were studied. The efficiency of ¹³⁷Cs recovery from large volumes of seawater by Termoxid sorbents under expeditionary conditions was evaluated.

通过在特莫克斯吸附剂上吸附从海水中回收铯-137

摘要介绍了在实验室和远征条件下使用市售 Termoxid 吸附剂（Termoxid 35 和 Termoxid 3A）从海水中回收铯的结果。测定了吸附剂对铯的动态交换能力和总动态交换能力。绘制了不同海水流速下的铯吸附突破曲线，并研究了吸附的物理化学关系（等温线和动力学）。评估了 Termoxid 吸附剂在远征条件下从大量海水中回收 137Cs 的效率。
