Additional information
Aluminum chemistry in natural water is extremely complex. Aluminum combines readily with a
number of elements and the resulting compounds may appear as both solid and dissolved forms.
Therefore, special attention must be paid to other ions found in the water to which alum is applied
and especially how these ions interact with the Al +3 ion and the AI(OH)3(s) polymer.
pH, interaction with other ions, concentration of substance are some factors which influence the both forms:
solid or dissolved.
Based on the physical-chemical properties of the substance and results of ecotoxicological information
(short-term and long-term aquatic toxicity of fish , aquatic invertebrates, aquatic algae/cyanobacteria,
toxicity to microoorganisms and terrestrial toxicity data) the substance is not classified for
environment according EU regulation EU 1272/2008 and EU regulation 286/2011 (2. ATP).
Conclusion on classification
The substance aluminium potassium bis(sulphate) is not classified for environment according CLP regulation EU 1272/2008
and EU regulation 286/2011 (2. ATP).
