M. Larroque et al., DETERMINATION OF ALUMINUM IN WINES BY DIRECT GRAPHITE-FURNACE ATOMIC-ABSORPTION SPECTROMETRY, Journal of AOAC International, 77(2), 1994, pp. 463-466
A simple method for direct routine determination of aluminum in wine b
y graphite furnace atomic absorption spectrometry is described. This p
rocedure allows good sensitivity by inclusion of a cool-down step befo
re atomization. The detection limit obtained with a single-beam appara
tus was 1.5 mu g/L. Recoveries of aluminum in red, white, and fortifie
d 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.
