Determines filterable (dissolved) and acid-soluble aluminium in potable waters, ground waters, and lightly polluted surface and sea waters. Coverage includes: reagents, apparatus, interferences and procedure.

1.1 Type of sample

The method is applicable to the analysis of potable waters, ground waters, and lightly polluted surface and sea waters.

1.2 Substance determined

The method determines filterable (dissolved) and acid-soluble aluminium.

1.3 Range

The method includes low range determination up to 100 µg/l Al with 50 mm cells and high range determination up to 500 µg/l Al with 10 mm cells. The effective range depends on the sensitivity of the spectrometer and can be extended upwards by taking smaller test portions.

1.4 Limit of detection

The limit of detection is 2 µg/l when cells of optical path length 50 mm and a 25 ml test portion are used.

1.5 Sensitivity

An aluminium concentration of 100 µg/l gives an absorbance of about 0,20 ± 0,05 optical absorption units, using a 25 ml test portion and cells of optical path length 10 mm.

1.6 Precision

If not specified, the precision of volumes and masses mentioned in this International Standard is ± 1 % of the value.
