摘要
研究了静态实验条件下,吸附平衡时间、酸度、温度对铯在焦磷酸氧锆上吸附的影响以及铯在不同酸度下的解吸,并研究了动态实验条件下,焦磷酸氧锆的吸附淋洗性能、焦磷酸氧锆从辐照靶件溶解液中提取铯的性能。结果表明:焦磷酸氧锆对铯的吸附约30min可达平衡;低酸低温有利于吸附,高温高酸有利于解吸;焦磷酸氧锆从辐照靶件溶解液中提取铯的回收率约为100%。
In the paper the adsorption behavior of cesium was studied. The effect of adsorp- tion equilibrium time, the temperature on the adsorption behavior of cesium and the effect of nitric acid concentration on the elution behavior of cesium were examined in static experi- ment. The adsorption behavior and the elution behavior of cesium were also investigated in dynamic experiment. Furthermore, the adsorption behavior and the elution behavior of cesium from high level liquid waste were also studied. Results show that the adsorption equilibrium time is about 30 min. The adsorption distribution coefficient decreases along with increasing the acid concentration and the temperature. In the dynamic tests with the mixed fission product elements solution, 137Cs in solution is almost all reclaimed.
