Abstract—

It has been demonstrated that titanyl hydrogen phosphate-based sorption materials can be effectively used for the extraction of cesium and strontium radionuclides from liquid radioactive waste similar in chemical composition to seawater. We have optimized conditions (pH, liquid : solid ratio, and temperature) for the coextraction of cesium and strontium cations. The titanium(IV) cesium or strontium double phosphate formed after heat treatment of the spent sorbent ensures proper immobilization of the radionuclides.

磷酸钛（IV）离子交换剂从溶液中萃取铯和锶阳离子

摘要—

已经证明，基于钛氧磷酸氢盐的吸附材料可以有效地用于从化学成分类似于海水的液态放射性废物中提取铯和锶放射性核素。我们已经优化了铯和锶阳离子共萃取的条件（pH，液体：固体比率和温度）。对废吸附剂进行热处理后形成的钛（IV）铯铯或磷酸锶锶可确保放射性核素的正确固定。
