【摘要】 本文研究了影响DNG(N,N-二壬基甘氨酸)萃取锗的各种因素,提出了用DNG萃取分离并纯化铂(Ⅳ)和锗(Ⅲ)的条件和工艺路线,用某厂Pt-Rh合金废料为原料进行小试,得到的金属纯度为:Pt 99.94％,Rh 99.93％,回收率:Ph 99％,Rh 90％。更多还原

【Abstract】 In this paper, several factors affecting the extraction of Rh(Ⅲ)with DNG (dinonylglycine) are studied, and the conditions and technology route of separation and purification of Pt(Ⅳ) and Rh(Ⅲ) by means of this process are developed . The purity of metals thus obtained is as follows: Pt 99.94% , Rh 99.93%. The recovery rate of Pt is 99% , and of Rh 90% , according to the test done with the scrap of the Pt-Rh alloy of some factory as raw material.更多还原
