Results and discussion
Water solubility
- Key result
- Water solubility:
- 0.005 g/L
- Conc. based on:
- test mat.
- Incubation duration:
- 1 d
- Temp.:
- 20 °C
- Remarks on result:
- other: Mean result
- Remarks:
- Standard deviation 4.63E-04 g/L
- Details on results:
- Calibration data gave a slope of 551977, an intercept of 53896 and a correlation coefficient of 0.99908, showing the detector response to be linear in the concentration range employed. Quality control data yielded a mean recovery of 102.0%.
Small peaks were observed at the retention volume of the test substance for the blank solutions, indicating the possibility of carryover.
Applicant's summary and conclusion
- Conclusions:
- The water solubility of simazine (pure) is 5.29E-03 g/L at 20°C.
