| Outline of Final Research Achievements |
In this study, we tried to recycle gold ions from industrial wastes and to synthesize nanomaterials from the recovered gold ions. Among five kinds of extractants which we have developed, N,N,N’,N’-tetra(n-octyl)diglycolamide (TODGA) showed high extraction separation performance for gold ions. Furthermore, we have succeeded in extracting selectively only gold ions from simulated industrial waste using microemulsions consisting of TODGA and surfactant AOT. Monodisperse gold nanoparticles were obtained by reduction of gold ions concentrated in the microemulsions. Unfortunately, the new method in this study failed to synthesize hollow nanomaterials.

| Academic Significance and Societal Importance of the Research Achievements |
本研究では安定確保が困難である金を産業廃棄物からリサイクルすることで、環境保全および資源の有効利用を目指すものである。環境・資源の視点から社会的に意義があり、資源循環システムの構築による持続可能な社会づくりへの貢献が期待できる。さらに、回収した金をナノ材料として再資源化することは学術的にも価値も高く、センシング、医療、フォトニクス材料などへの応用が期待される。
