Materials and methods
Test guideline
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.6 (Water Solubility)
- Version / remarks:
- yes (High purity water was used instead of glass-double distilled water; No glass was used in critical sample preparation and handling steps)
- Principles of method if other than guideline:
- Due to the necessity to analyse for silicon, approximately 18 MΩ high purity water was used as an alternative to glass-double distilled water during the preliminary test and the definitive test whilst monitoring
minor components/impurities. It was not appropriate to use water prepared in a glass apparatus due to potential interferences on analysis and in addition, the use of glass was also excluded from critical
sample preparation and handling steps. This deviation was not considered to impact on the validity of the determinations, but was an essential step to generate reliable dissolved silicon data. Glass-doubledistilled
water was used for the definitive test calcium determination. - GLP compliance:
- yes (incl. QA statement)
- Type of method:
- flask method

- Remarks on result:
- other: This is the water solubility of aluminium as determined in the study. Variation of temperature was ± 0.5 °C.
- Details on results:
- The preliminary test results indicated that, with exception of one sample (nominal lading rate of 1.0 g/L), no loading rate dependent solubility characterisitcs were observed. For the one sample, elevated
alumnium and silicon concentrations were detected, but it was immediatley obvious that the sample solution was not saturated with respect to the dominant element, calcium. Therefore, this loading rate was
not suitable for the definitive test determination, which should be prepared typically at five times the concentration required to achieve saturation. The reduced calcium concentration of this sample, due to
insufficient test material being present to achieve saturation, possibly allowed the additional dissolution of the aluminium and silicon containing components.
For the definite test (minor components and impurites) an increasing trend in solubilised alumnium concentration with initial saturation time was observed. However, as solubility remained low (<0.2 mg/l)
even after an initial saturation period of 72 hours at 30 °C, no additional testing was considered necessary.
Applicant's summary and conclusion
- Conclusions:
- Interpretation of results (migrated information): slightly soluble (0.1-100 mg/L)
The water solubility has been determined for four components of lime (chemical) hydraulic. The four components and the water solubility of these are as follows:
1) 1010 mg calcium/L at 20.0 ± 0.5 °C
2) 0.158 mg aluminium/l at 20.0 ± 0.5 °C
3) 0.305 mg silicon/l at 20.0 ± 0.5 °C
4) 0.115 mg iron /l at 20.0 ± 0.5 °C.
An exact water solubility of lime (chemical) hydraulic can not be determined since the molecular formula of the test item is unknown. However, since calcium is the main component of the test material it can
be assumed that the test item is soluble in water.
