【摘要】 本文以¹⁹⁷Pt、¹⁰³Pd和¹⁹²Ir为示踪原子,用离子交换法研究了常量Rh和小量Pt、Pd、Ir的分离。将Rh和Pt、Pd、Ir的盐酸溶液通过阳离子交换树脂往后,先用1M H Cl淋出Pt、Pd和Ir后,再用6M H Cl淋出Rh使Rh和Pt、Pd、Ir得到定量分离。更多还原

【Abstract】 The separation of pure Rh from a solution containing Pt, Pd and Ir on a cation exchanger column was studied by using radioactive nuclides 197Pt, 103Pd and 192Ir as tracers. A diluted H Cl solution of the noble metal mixture was loaded for ion-exchange. Pt, Pd and Ir were first eluted out from the column with 1M H Cl, and then Rh could be sub-sequntly eluted out by 6M H Cl. Rh was quantitatively separated from Pt, Pd and Ir.更多还原
