- Details on study design:
- A predeterminated amount of the test substance FAT - 36'034/D in water is oxidized by potassium dichromate in a strong sulphuric acid medium with silver sulphate as a catalyst under reflux for 2 hours. The residual dichromate is determined by titration with standardized ferrous ammonium sulphate.
The test substance was tested with a sample weight of 4.82 + 5.07 mg. The reference substance Potassium hydrogen phthalate solution was tested in a concentration of 20 ml/l. - Reference substance:
- other: Potassium hydrogen phthalate solution (Merck-Nr. 11769)
- Remarks on result:
- not measured/tested
- Parameter:
- COD
- Value:
- 1 747 mg O2/g test mat.
- Validity criteria fulfilled:
- not specified
- Interpretation of results:
- other: COD determined
- Conclusions:
- The COD of FAT 36034/D is found to be 1747 mg O2/g.
- Executive summary:
The study describes the experimental techniques and the results obtained in a COD test of FAT 36034/D. The study was performed in accordance with DIN 38409 -H41 -1.
The COD of FAT 36034/D is found to be 1747 mg O2/g.

Additional information
A study was performed to determine the COD value of FAT 36034/D, by following the guideline DEV DIN 38409 - H 41-1 (1980) corresponding to 92/96/EE C C.6., in compliance with the Good Laboratory Practice (GLP) Regulations. A predetermined amount of the test substance FAT 36034/D in water was oxidized by potassium dichromate in a strong sulphuric acid medium with silver sulphate as a catalyst under reflux for 2 hours. The residual dichromate was determined by titration with standardized ferrous ammonium sulphate. The reference substance Potassium hydrogen phthalate solution was tested in a concentration of 20 ml/l. The COD of FAT 36034/D and reference substance was found to be 1747 mg O2/g and 196 mg O2/I respectively. The study reported the value of greater than 1000 mg /g O2 for COD. Relevant is the BOD5/COD quotient which is not > 0.5 , therefore the substance is not indicative of rapid degradation. Taking all data into consideration, the test substance FAT 36034 is considered to be not biodegradable.
