Results: HPLC method
- Details on results (HPLC method):
- In the chromatogram of the test substance solution, one peak with a retention time of 1.15 minutes was observed. Under the same analytical conditions, the retention time of acetanilide (log Koc (soil) = 1.26, log Koc (sewage sludge) = 1.52) was 2.28 minutes. Hence, it was concluded that the log Koc(soil) of the test substance was < 1.3 (Koc < 18) whereas the log Koc (sewage sludge) was < 1.52 (Koc < 33).
Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Conclusions:
- The HPLC method using soil/sewage sludge-adsorption-reference data was applied for the determination of the adsorption coefficient (Koc) of E-BW102. The Koc and log Koc values (soil) of the test substance at neutral pH were < 18 and < 1.3, respectively. The values for Koc and log Koc (sewage sludge) at netural pH were < 33 and < 1.52, respectively.
