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、铂的工艺过程。
Abstract: The extraction properties of precious metals by petroleum sulphoxide have been studies. An inte-grated solvent extraction method used to separate gold, palladium and platinum in distillated raffinate from Jingchuan Non-ferrous Metals Industry Companywas proposed, which sonsisted of the extractions of gold by DBC, palladium by PSO and platinum by N235.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.
