摘要
We describe herein an environmentally benign strategy for removing of fission products from spent nuclear fuel by the selective dissolution using carboxyl-functionalized ionic liquid[Hbet][Tf2N].Water-statured[Hbet][Tf2N]can dissolve lanthanides oxide from simulated spent nuclear fuel with a dissolution ratio of 100%at 40℃.However,the dissolution of uranium is almost neglect(<1%)under the same conditions.This process of separation displays an outstanding performance to separate some key fission products oxide such as neutron poisons Ln2O3 efficiently and allows the recovery of actinides AnO2 as a group in solid form.
