UO$$_{2}$$とCeO$$_{2}$$を溶解したモリブデン酸溶融塩中で電解操作で得られた析出物を分析した結果、ウランに対するCeのDFは35となった。EDS分析の結果、Ceは析出物に付着する塩に同伴していた。

Deposits which include uranium and cerium was recovered on cathode by electrolysis in the mixture of uranium molybdate and cerium molybdate. Decontamination factor of cerium for uranium was evaluated as 35. And from the result of EDs analysis, cerium was contained in adhererd salt.
