Solvent extraction of precious metals by N and S donor extractants

Tsuchida, Yusuke; Matsumiya, Masahiko*; Sasaki, Yuji ; Akama, Takeshi*; Arita, Yuji*

We study the solvent extraction of soft acid metals, e.g., platinum metals, gold and silver from nitric and hydrochloric acids by commercially available organic compounds with low solubility in water. We would like to know some of the physical parameters obtained from DFT calculations can support the experimental results. The present work show that the extractants having S-donor give high extractability for gold.
