摘要
ＩｒＯｓ矿经碎化，碱熔，酸浸出。Ｐｔ－Ｒｕ－Ｉｒ合金用封管氯化法制成氯络合盐溶液。高锰酸钾－溴酸钠氧化除Ｏｓ、Ｒｕ。
Osmite was powdered,fused by base,and immersed out by acid.Pt-Ru-Ir alloys were chlorodized to the solutions of chloroiridate complexes in sealed tube.Osmium and ruthenium were removed by oxidation with KMnO4-NaBrO3,then iridium was determinated amperometrically by FeSO4.
