Abstract
Abstract A simple method for direct routine determination of aluminum in wine by graphite furnace atomic absorption spectrometry is described. This procedure allows good sensitivity by inclusion of a cool-down step before atomization. The detection limit obtained with a single-beam apparatus was 1.5 μg/L. Recoveries of aluminum in red, white, and fortified wines ranged from 91.7 to 109.5%. Aluminum was determined in 98 red table wines from the south of France. The mean aluminum content was 0.763 mg/L (range, 0.25–2.55 mg/L). In addition, the ability of the wine to dissolve the aluminum in the crown cap was shown.
