摘要
该文研究并建立了测定微量锇的新体系,即α,β,γ,δ-四-（4-磺基苯基）卟啉与锇的显色反应。确定了反应的最佳条件。实验证明,该法灵敏度高,稳定性好。采用三正辛胺离子交换树脂分离富集锇,对合成样及贵金属分析样进行测定,结果令人满意.
In this paper, a new system for the determination of microamounts of Osmium has been initially studied and suggested, it has been the colour reaction of Osmium with α, β, γ, δ-tetrakis- (4-sulphophenyl) porphine. The optimum conditions of the reaction has been established. The experiment has been proved that this method has high sensitivity and good stability. The proposed method has been applied to determine Osmium (Ⅳ) in the synthetic samples and the noble metals analytical samples after it was separated and concentrated with Trioctyl Amine (TOA) ion exchange resin, and obtained satisfactory results.
