Abstract
This paper describes an analytical method for the quantitation of iron, cobalt, nickel, and copper at trace levels with graphite furnace-atomic absorption spectrometry (GF-AAS) without the use of any matrix modifier or preconcentration techniques. A solution of HfF4 (10%, w/v) in HF (24%) was used for this study. The detection limits for iron, cobalt, nickel, and copper were found to be 3, 1, 3, and 2 ppb, respectively. The average precision of measurements (% RSD) for all the elements was <10%.
