Analytical Method The determination of copper in fused mixtures of sodium, zirconium and uranium fluorides

摘要

The sample is fused with potassium pyrosulphate and the resulting melt dissolved in 0. 5 M sulphuric acid. Copper is determined after reduction by reaction with 2 :2' diquinolyl. The copper complex is extracted into n hexyl alcohol and the absorbancy of the extract is measured at 540 mμ.
