Aluminium, Al (acid-soluble)

Last changed: 21 May 2021

The sample is acidified, but not heated, wereafter aluminium is quantified colourimetrically. The method estimate the bulk of dissolved aluminium, but only a small amount of aluminium bound in e.g. mineral particles, since the treatment is too mild to disintegrate the particles. 

Known issues with the parameter and/or important method changes

Aluminium can be analysed with several different methods. Read more in our method comparison (in Swedish).

Current method of measurement

The analysis method ceased in 2003.
