Results and discussion
Water solubility
- Water solubility:
- < 0.1 mg/L
- Conc. based on:
- test mat.
- Temp.:
- 20 °C
- pH:
- > 6.1 - < 6.9
- Details on results:
- The detector calibration was found to be linear over the range 0 to 1 mg/l of standard solutions in 0.2% v/v aqueous nitric acid with a regression coefficient of 0.9995.
The water solubility of test substance is less than 0.1 mg/l.
A mean recovery of approximately 93% of titanium from fortified control samples was achieved and deemed to be acceptable, whilst no significant interference was evident in blank
control solutions.
Applicant's summary and conclusion
- Conclusions:
- Test substance was found to have a water solubility of less than 0.1 mg/l at 20 °C.
