Abstract

The adsorption behavior of silica gel for Zr, Pu and fission products (Fe, Mo, Nd, etc.) in high-level liquid waste (HLLW) have been studied. The dynamic desorption for Zr and Pu are also investigated. Silica gel is found to have high selectivity for Zr to other elements in HLLW and its adsorption capacity can be enhanced by H₂C₂O₄ elution and multiple reuse. However, the adsorption for Pu(IV) is also found. This may cause spent silica gel to be alpha waste. Further study should be carried out on the adsorption behavior for Pu(IV).
