Abstract:
The flame atomic absorption spectrometric determination of copper, zinc, calcium, magnesium and iron in fresh eggs using a microvolume injection technique is described. The capillary tube and glass impact bead were removed from the nebulizer and a polypropylene tube was installed in the inlet of the capillary tube of the nebulizer as the interface for microvolume injection. The injection volume was 10 mul and calibration was carried out using aqueous standards. Beer's law was obeyed in the concentration ranges of 0.1-1.5, 0.1-3.0, 0.2-4.0, 0.5-4.0 and 1.0-6.0 mg 1(-1) for Cu, Zn, Ca, Mg and Fe, respectively, and the detection limits were 0.016, 0.016, 0.035, 0.010 and 0.10 mg 1(-1), respectively. The reliability of the measurements was confirmed by analyzing a certified reference material, GBW 08551 Pork Liver. The precision was 2.6, 2.9, 3.0, 1.3 and 2.5% for Cu, Zn, Ca, Mg and Fe, respectively. The recovery with the standard additions method was good, ranging from 96.2 to 100.0%.
