Abstract
【解決手段】 極性希釈剤中に二座配位の有機リン抽出剤であるオクチルフェニル-N,N-ジイソブチルカルバモイルフォスフィンオキシドを含む溶液からなる混合抽出剤であって、上記極性希釈剤としてメタニトロベンゾトリフルオライド(MNBTF)とTBPの混合物を使用し、かつ上記オクチルフェニル-N,N-ジイソブチルカルバモイルフォスフィンオキシドを0.1〜1.2M/Lとするとともに、上記TBPを0.3〜1.1M/Lとした酸性溶液中のアクチニド元素を回収するための混合抽出剤である。
【選択図】なし
Description
極性希釈剤フルオロポール-1083中に30%(HexO)2/Et2を含む混合抽出剤を、金属(U、TRU、Eu)の硝酸塩を含むHNO3溶液と、20℃で3分間接触させた。分配係数を図1と表1に示す。
極性希釈剤フルオロポール-1083中に30% (HexO)2/Et2を含む混合抽出剤による、硝酸ウラニル(水相中のウランの初期濃度−100g/L)を含む2M HNO3からのU、TRUおよびEuの抽出
極性希釈剤フルオロポール-1083中に30%(HexO)2/Et2を含む混合抽出剤を、種々の濃度の硝酸ウラニルを含むHNO3溶液と、20℃で3分間接触させた。分配係数を図2に示す。
ドデカン中に0.2M オクチルフェニル-N,N-ジイソブチルカルバモイルフォスフィンオキシドと1.1M TBPを含む混合抽出剤を、種々の濃度の硝酸ウラニルを含むHNO3溶液と、20℃で3分間接触させた。10g/Lを超えるウラン濃度では、抽出中に第三相が生成し、30g/Lを超えるウラン濃度では、沈殿が認められた(表2参照)。
極性希釈剤メタニトロベンゾトリフルオライド(MNBTF)中に0.1M ジフェニル-N,N-ジブチルカルバモイルフォスフィンオキシドを含む混合抽出剤を、種々の濃度の硝酸ウラニルを含むHNO3溶液と、20℃で3分間接触させた。初期水溶液中のウラン濃度が5g/Lを超えると、抽出プロセス中に沈殿が認められた。
本発明の混合抽出剤とプロトタイプとの比較も表2に示す。
