摘要
研究Ｐｄ－Ｎｉ－Ｒｕ和Ｐｔ－ｐｄ－Ｒｈ－Ｒｕ合金中Ｒｕ的测定方法。合金以锌碎化进行强化预处理，然后经碱熔、水浸和蒸馏，馏出液经浓缩富集后用硫脲显色。此法适用于合金中０．１～１．０％含量Ｒｕ的测定。
method for the determination of Ru in Pd-Ni-Ru or Pt-Pd-Rh-Ru alloys has been developed.These alloys were fragmentized by fusion with zinc,and then fused with alkali,leached and distilled.The distillation was concentrated,colored with thiourea.This method can be applied to determine Ru of content 0.1～1.0%in alloys.
