Outline of Final Research Achievements

This research was investigated the novel recycling technology for precious metals recovery combined with halogen leaching and pincer type extractant.
In the halogen leaching method, more than 98% of gold was recovered from incinerated ash of wasted electronic circuit board (E-waste) by the iodine leaching and the precipitation method.
Moreover, pincer-type ligand as new effective Pd(II) extractant, 1,3-bis(2-(octylthio)propan-2-yl)benzene (1), was synthesized, and its ability to extract Pd(II) from HCl and HNO3 media was studied. The 1 showed superior Pd(II) extractability (E% = 99.9) relative to DOS from HCl and mixed HCl + HNO3 media. Selective extraction of Pd(II) by 1 was achieved from the leach liquors of automotive catalysts containing Pd, Pt, Rh, rare metals, and base metal ions.

Academic Significance and Societal Importance of the Research Achievements

貴金属等の酸溶解では一般に強酸溶液を使用するが、本研究では、ヨウ素-ヨウ化物溶液により金を選択的に溶解し、溶液中の錯イオン形成や金の沈殿回収プロセスを明らかにした。また、廃電子基板焼却灰に含まれる金の98%以上を回収できるなど、新たなリサイクル技術の可能性を提案した。一方、新たに開発したカニばさみ(Pincer)型抽出剤は、パラジウムに高選択性を有するほか、抽出能力が極めて高く、酸への安定性が高いなど、優れた特性を有することがわかった。また、逆抽出も可能で、自動車排ガス触媒の塩酸浸出液からパラジウムのみを繰り返し抽出が可能で、実用性が高く、学術的価値の高い研究成果を得ることができた。
