Endpoint:
water solubility
Type of information:
experimental study
Adequacy of study:
key study
Study period:
Aug 2018
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
study well documented, meets generally accepted scientific principles, acceptable for assessment
Qualifier:
no guideline followed
Principles of method if other than guideline:
1.0000 gram +/- 0.005 g reference material was weighed into a 100 mL beaker. 25 mL ultrapure water (≥ 18.2 MΩ) was added. The mixture was stirred on a magnetic stirrer for 15 minutes. The resulting mixture was filtrated over an ashfree filter paper (Whatman Cat No 1440-150).
5 mL of the filtrate was pipetted into a 50 mL volumetric flask. 50 μL yttrium reference standard 1000 ppm was pipetted into the volumetric flask. 2 mL hydrochloric acid 36% was added to the volumetric flask. The volumetric flask was made up to volume with ultrapure water (≥ 18.2 MΩ).
The sample preparation was carried out in duplicate.
