Description
(2)クエン酸、EDTA(エチレンジアミン四酢酸)のような錯形成剤では、使用で
きるpH条件が高く(pH>3)、Pu(IV)の水酸化物沈殿する可能性がある。硝酸溶液でも使用可能なシュウ酸はPu(IV)と沈殿を生成し、またDTPA(ジエチレントリアミン五酢酸)に関しては硝酸溶液への溶解度が低い(最大50mM程度)。これらの錯形成剤は下の参考文献1−3で参照できる(非特許文献1,2及び3)。

(1)0.2M硝酸の条件でAm(III),Pu(IV)の低い分配比を
示し、3M硝酸でもPu(IV)の低い分配比を示す。
(3)炭素、水素、酸素、窒素からなり構造内にリンを含まない化合物である。
(4)還元剤を加える必要がない。
TMDGAを用いて、Pu(IV)及びAm(III)の抽出分配比を測定した。水相に各アクチノイドイオンとTMDGAを含む0.2M硝酸溶液を、有機相に0.2M TODGA/n−ドデカン溶媒を用いて、得られた分配比をTMDGA濃度に対してプロットした。その結果を図1に示す。図1に示されるように、TMDGA濃度が増加するとともにPu(IV),Am(III)分配比は減少し、TMDGA濃度0.1Mで、Pu(IV)及びAm(III)それぞれの分配比は0.01以下であった。なお、TMDGAが存在しない条件で0.2M TODGA/n−ドデカン−0.2M硝酸条件での分配比はPu(IV)が3で、Am(III)が1.46であった。したがって、TMDGAは、その濃度が低くてもPu(IV)及びAm(III)の抽出が良好に行われることを示している。
実施例2
TMDGAを用いて、Pu(IV),Am(III)の抽出分配比を測定した。水相にアクチノイドイオンと0.1M TMDGAを含む硝酸溶液、有機相に0.2M TODGA/n−ドデカン溶媒を用いて、得られた分配比を硝酸濃度に対してプロットした。その結果を図2に示す。図2に示されるように、0.1M TMDGAを含む0.64M硝酸溶液を用いて、Pu(IV),Am(III)分配比はそれぞれ0.002,0.017であり、これ以下の酸濃度条件で一括逆抽出が可能である。なお、Pu(IV)に対して、3M HNO3の条件でも分配比は0.1以下であり、この条件を用いれば、単独にPu(IV)のみを逆抽出する事が出来る。
Claims (1)
- TODGA(N,N,N',N'−テトラオクチル−1,3−オキサペンタンジアミド)を抽出剤として用いてn−ドデカン溶媒に抽出した後のAm(III),Pu(IV)の3,4価のアクチノイドイオンを、TMDGA(N,N,N’,N’−テトラメチル−ジグリコールアミド)により、硝酸溶液中に逆抽出する方法。
