[en] A method for determination of Fe, Mn and Pb in red wine samples was developed by the graphite furnace atomic absorption spectrometric. Several different matrix modifiers were necessary because of evident analyte losses that occurred immediately in sample incineration. Red wine samples were analyzed after microwave digestion using HNO_3. Standard addition method was used, the calibration concentration was 1 ng · ml"-"1, 3 ng · ml"-"1, 5 ng · ml"-"1 which containing 580 μg/ml KNO_3 as matrix and 0.2% HNO_3. The correlation coefficient of the calibration line was very good within the measurement area. The recovery with red wine sample was very good at the range from 95%-107.5%. (authors)
