Outline of Final Research Achievements

In this study, valence conversion of metal ions using photocatalytic reaction was applied to control the extraction behavior of solvent extraction. The photocatalytic reaction was able to control the valence of metal ions and improved solvent extraction efficiency. Furthermore, by combining an emulsion flow reactor and a semi-hydrophobic photocatalyst, we have developed a highly efficient reaction device that can use and retain the catalyst with a high dispersion condition.

Academic Significance and Societal Importance of the Research Achievements

本研究は、従来の溶媒抽出法で問題となっていた、化学的に似通った元素同士の相互分離性の向上に資するものであり、光触媒反応による金属イオンの価数変換と溶媒抽出を併せた新しいシステムは学術的意義に富む。また、本研究で提案する新しい液-固-液反応装置はこれまでの不均一触媒を用いた処理における問題であった反応効率とプロセスの簡略化の両立を可能にするものであり、社会的意義は大きい。
