基于丙酮在吐温４０一氢氧化钾一过氧化氢一O_ｓ（Ⅳ）体系中增强Ｏ_ｓ（Ⅳ）的化学发光，采用流动注射进样技术，建立了测定痕量锇（Ⅳ）的新的化学发光分析法．方法的线性范围为１．０Ｘ１~－８～１．０Ｘ１０~－６Ｏ（Ⅳ）／ｍＬ检出限为２．０Ｘ１０~－９ｇ／ｍ，对１０Ｘ１０~－７ｇ／ｍＬＯｓ（Ⅳ）标准溶液测定１１次的相对标准偏差为３．０％．拟定方法用于贵金属精矿中痕量锇的测定，结果满意。本文还进行了增敏机理的探讨．
Based on the enhanced chemiluminescence of O_s (Ⅳ) with acetone over Tween 40-OH-O-O (Ⅳ) system, a new chemistry for the determination of trace osmium (Ⅳ) Luminescence analysis. The linear range of the method is 1.0X1 ~ -8 ~ 1.0X10 ~ -6O (Ⅳ) / mL with the detection limit of 2.0X10 ~ -9g / m, and the standard solution of 10X10 ~ -7g / mLOs The relative standard deviation was 3.0%. The proposed method was applied to the determination of trace osmium in precious metal concentrates with satisfactory results. This article also conducted a sensitization mechanism.
