摘要
研究了铂铱合金中测定铱的氧化还原滴定法。对氧化条件、氯水用量、通气流量、时间及Pd、Rh、Ru等共存元素的影响进行了实验,拟定了分析方法。对合成试样及合金样品进行了测定,当铱含量为25.0%时标准偏差为0.044%。
Determination of Ir in Pt - Ir alloys by the oxidation - reduction titration was studied. The influences of the oxidation conditions, the consumption of Cl2 - bearing water, the rate of flow and time for inletting air ,and the coexisting elements, such as Pd, Rh and Ru were discussed. An analytical method was developed, to determine the synthetic samples and Pt- Ir alloys . The standard deviation of 0.044% can be achieved when the content of Ir is 25.0%.
