Abstract  

Determination of Hf using Inductively Coupled Plasma Spectrometry down to 100 ppm and less in Zr matrix has been studied. Standard additions method has been applied for determination of Hf at different Hf wavelengths. Additionally, Hf was determined after its separation from Zr matrix using AG 1-X8 Biorad anion exchange resin. It has been observed that hf content determined following standard additions method at Hf line 356.166 nm compared well with the results obtained using prior separation method.
