Aluminium determination in bottled mineral waters by electrothermal atomic absorption spectrometry
1995
Plessi, M. | Monzani, A.
Over one hundred samples of natural mineral waters corresponding to 43 different domestic and foreign brands were analyzed for the aluminum content by electrothermal atomic absorption spectrometry. Good reproducibility. sensitivity, and rapidity make the method convenient for routine aluminum determination. The calibration curve was linear from 1.9 to 80 ng/ml and the detection limit was 1.9 ng/ml (characteristic mass 38 pg Al, with 20-microliter injections). The levels of aluminum in the waters examined were very low, and none of the samples tested exceeded the EEC guideline value of 50 micrograms/liter.
