摘要
阐述了石油亚砜（ＰＳＯ）选择性萃取分离Ｐｄ的基本原理，并以此为基础研究了用ＤＢＣ萃Ａｕ、ＰＳＯ萃Ｐｄ及Ｎ２３５萃Ｐｔ，从金川蒸馏Ｏｓ、Ｒｕ之后的脱胶液中萃取分离金、钯。
The extraction properties of precious metals by petroleum sulphoxide have been studied. An integrated solvent extraction method used to separate gold, palladium and platinum in distillated raffinate from Jingchuan Non ferrous Metals Industry Company was proposed, which consisted of the extractions of gold by DBC, palladium by PSO and platinum by N 235 . The percent extractions and strippings of Au, Pd and Pt have all come up to the standard of 99 99%. The rhodium and iridium mainly retained in the raffinate.
