AI Article Synopsis
- The study details a refined spectrophotometric method for simultaneously measuring zirconium and hafnium using a combination of hydrogen peroxide, sodium sulfate, and excess zirconium ions with Xylenol Orange in a perchloric acid solution.
- Isolation methods were developed to extract hafnium and zirconium from complex high-temperature alloys, ensuring the ionic substrate is suitable for the spectrophotometric analysis.
- The approach emphasizes the compatibility of the masking technique with the ionic conditions necessary for accurate determination of the elements in the sample.
Article Abstract
Data are presented for a refined spectrophotometric procedure for the simultaneous determination of zirconium and hafnium based on the combined effects of hydrogen peroxide, sodium sulphate, and excess of zirconium ion on the hafnium and zirconium complexes with Xylenol Orange in 0.2M perchloric acid. Isolation procedures for the hafnium/zirconium content of complex high-temperature alloys which result in an ionic substrate compatible with the spectrophotometric masking method were devised.
