Outline of Final Research Achievements

Adsorption behavior of betaine-type polymer for Pd(II), Rh(III), and Ru(III) were studied using XAFS (X-ray absorption fine structure) and FT-IR (Fourier Transform Infrared) spectroscopies. The polymer adsorbed the Pd(II), Rh(III), and Ru(III), and hardly Cu(II) and Ni(II). The XAFS and FT-IR spectra revealed that carboxylate moieties on the AMP03 cause the adsorption reaction of the platinum group ions via coordination or cation exchanges for the ions.

Academic Significance and Societal Importance of the Research Achievements

白金族金属の製錬において、一般的に塩酸や王水で浸出が行なわれる。したがって、これらの溶液中の白金族金属の分離研究は、広く行われている。一方、原子力分野や銀を含む白金族金属の製錬においては、硝酸溶液からの分離が必要になるが、分離剤に関する知見は、これまでにほとんどなかった。そこで本研究では、硝酸水溶液中の白金族イオンを吸着するベタイン型ポリマーのメカニズム解明を行なった。
