摘要
本文报导了用DBC-CPA直接分光光度法测定钛合金中Nd。测定范围0.01～0.16％,表观摩尔吸光系数ε_(645nm)=8.1×10~4,在0～8μg/25ml范围内符合比尔定律。方法的相对标准偏差小于10％,回收率为95～105％。
A method has been developed for the determination of neodymium in titanium alloys. A color reaction based on DBC-CPA with neodymium has been investigated. The optimum condition is recommended. This procedure can be used for the samples that contain neodymium with a concentration range of 0.01-0.16%. The apparent molar absorptivity is 8.1X104 at 64Snm. The analytical results are satisfactory. The advantages of the proposed method are its simplicity, accuracy, and high speed of analysis.
