Chromatographic Separation of Actinides and Fission Products

Several novel adsorbents which are immobilized in a porous silica/polymer composite support (SiO2-P) were prepared to separate MA (Am, Cm) and some fission product elements (FPs) such as Tc, Pd, Cs and Sr from high level liquid waste (HLLW) by chromatographic techniques systematically. Adsorption and separation behavior of various elements contained in HLLW was studied experimentally. Small scale separation tests using simulated and genuine waste solutions were carried out to verify the feasibility of the proposed process. The obtained experiment results indicated that the proposed process is essentially feasible.
