Abstract:

Zirconyl pyrophosphate (ZrP2O7) was prepared and Cs adsorption behavior was studied. Results show that the distribution coefficient of Cs adsorption on ZrP2O7 was about 2800 mL/g. Ion exchange capacity of ZrP2O7 was 0.35 mmol/g. In dynamic tests, Cs can be separated from other fission products very well by ZrP2O7. The ZrP2O7 was stable both at high temperatures and in high concentration of nitric acid. The Cs adsorption by ZrP2O7 is a monolayer and chemical adsorption.

Key words: Zirconyl pyrophosphate, Adsorbent, Cesium
