Conc. based on:

Temp.:

Remarks on result:
other: concentration of Sulphur in water
Details on results:
At the plateau, the concentration of Aluminium in water had reached
252.1 ± 9.8 mg/L Al at 20.0 ± 0.5 °C
= 2.521 ± 0.098 * 10-1 kg/m3 (SI units)
(mean value ± standard deviation of six individual vessels, nominal load 50 g/L)

The concentration of Sulphur in water had reached
517.7 ± 24.7 mg/L S at 20.0 ± 0.5 °C
= 5.177 ± 0.247 * 10-1 kg/m3 (SI units)
(mean value ± standard deviation of six individual vessels, nominal load 50 g/L)

A partial solubility of the test item was observed due to the release of different ions from the test item (0.50 % Al and 1.04 % S, calculated from the nominal load of 50 g/L).

No Tyndall effect (i.e. a laser beam was not scattered when transmitted through the liquid) could be observed indicating that no colloidal dispersed particles are present.
The measured aluminium and sulphur concentrations showed good correspondence in all flasks. Therefore, all replicates were used in the calculation of the mean.

Applicant's summary and conclusion

Conclusions:
Test item is poorly soluble: Aluminium reached 252 mg/L and Sulphur 518 mg/L (at 20°C)
