- Conclusions:
- Octanol/water partition coefficient of Phenoxycycloposphazene was 3.26±0.04. And this value of Log Pow is greater than 3. Thus, the test substance could be classfied as a high bio-concentrative chemical substance in the aquatic environment.
- Executive summary:
The results of Octanol/water partition coefficient of Phenoxycycloposphazene were as follows:
(1) The recoveries of the test substance Phenoxycycloposphazene, were 104.73±3.17% in 1 -octanol phase and 99.67±0.31% in water phase, respectively.
(2) The values of log Pow treated three different volume ratios of test substance solution were calculated to be 3.25±0.03, 3.22±0.01 and 3.30±0.06, respectively.
As a result, Octanol/water partition coefficient of Phenoxycycloposphazene was 3.26±0.04. And this value of Log Pow is greater than 3. Thus, the test substance could be classfied as a high bio-concentrative chemical substance in the aquatic environment.
