Method for measuring rhodium and iridium in gold separation slag

The invention discloses a method for measuring rhodium and iridium in gold separation slag. A sulfonium nickel button rich in rhodium and iridium is prepared, the sulfonium nickel button is dissolved with hydrochloric acid to effectively separate to-be-detected precious metal sulfide and impurity elements, suction filtration is carried out while the sulfonium nickel button is hot, a tellurium coprecipitation link is omitted, an analysis process is simplified, and rhodium and iridium in the precious metal sulfide can be completely dissolved through sealed digestion. 本发明公开了一种测定分金渣中铑和铱的方法，首先制备得到富集铑和铱的锍镍扣，锍镍扣通过盐酸溶解可以有效分离待测贵金属硫化物和杂质元素，趁热抽滤，省略碲共沉淀环节，简化了分析流程，密封消解可以将贵金属硫化物中铑和铱完全溶解。
