Determination of Cu, Zn, Fe and Cd in Finger Nails by Flame Atomic Absorption Spectrometry with Solvent Extraction Technique |
| |
| Abstract: | A method was proposed for the determination of Cu, Zn, Fe and Cd in finger nails in this paper with flame atomic absorption spectrometry (FAAS) using solvent extraction technique. The experimental conditions which affect the extraction efficiency and the sensitivity of the method were investigated and optimized. The proposed method was applied to the determination of Cu, Zn, Cd and Fe in finger nails with a recovery range of 93%～106%. |
