摘要
本文研究了二正已基硫醚对铂、钯的萃取分离。在0.1MHCI条件下,用DHS一二甲苯溶液作萃取剂,能选择性地萃取pd(Ⅱ),而与pt(Ⅳ)定量分离。载钯有机相用氨水反萃,一级反萃率即高达98.25%。
The extraction seperation of platinum and palladium by means of dihexylsu-fide has been studied. In 0.1M HCL, the dihexylsulfidexylene used as an extrac-tant can selectively extract Pd(II) and so can quantitatively separate it from aqueous solution containing Pt(IV). The loaded organic phase can be stripped with ammonia, the effciency of the first stage being as high as 98.25%.
