Spectroscopic analysis for extraction of Pt(IV) with amide and urea type extractants

Ueda, Yuki; Sugita, Tsuyoshi; Okamura, Hiroyuki; Shimojo, Kojiro; Naganawa, Hirochika; Morisada, Shintaro*; Kawakita, Hidetaka*; Oto, Keisuke*

Platinum group metals (PGMs) are indispensable metals in modern industries and are used for example as active components in automobile gas catalysts, jewellery goods, electronic devices and dental materials. In order to meet the growing demand, high efficient receptors for liquid-liquid extraction of the respective anionic chloro-complexes are required in order to enhance capable winning from either pour geological deposits or complex secondary sources within the Urban Mining. The ligand containing urea or amide groups can form the hydrogen bond with anionic species. The novel urea or amide containing extractants were synthesized and its extraction behavior and mechanism were investigated in this work.
