Key result
Water solubility:
0.44 mg/L
Conc. based on:
test mat. (total fraction)
Incubation duration:
74 h
Temp.:
20 °C
pH:
6.8 - 7.1
Details on results:
The following concentrations were measured in the solutions saturated by the 24 hours shake-flask experiment: 1.9; 1.8 and 1.5 mg/L. The mean value is 1.7 mg/L.
Based on this value the column elution method was applied in the course of the main study.
Conclusions:
The water solubility of the test item was determined to be 0.44 mg/L at 20°C at a pH-value of 6.8-7.1.
Executive summary:

The study was conducted according to EC method A.6, using the column-elution method. After the equilibrium was reached measured pH values varied between 6.8 and 7.1. In conclusion, the water solubility of the test item was determined to be 0.44 mg/L at 20°C.
