Determination of trace impurities in high-purity niobium by inductively coupled plasma atomic emission spectrometry after anion-exchange separation

Inductively coupled plasma atomic emission spectrometry (ICP-AES) in combination with anion exchange with hydrochloric and hydrofluoric acid media was applied to the determination of trace-metal impurities in high-purity Nb samples. The column operating conditions of the anion-exchange method were s...
