EC number: 266-648-3 | CAS number: 67338-59-4
COD = 1412 mg O2/g
The test was carried out according to DEV DIN 38'409 - H 41-1 (1980) corresponding to 92/96/EEC C.6. The test was performed in compliance with the Good Laboratory Practice (GLP) Regulations of Switzerland.
A predeterminated amount of the test substance 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 7.39 + 7.11 mg. The reference substance Potassium hydrogen phthalate solution was tested in a concentration of 20 ml/I.
The COD of test item is 1412 mg O2/g
The COD of the reference substance is 201 mg O2/I
The degradation after 14 days of the reference substance (Natriumbenzoat) has to be higher than 65 %.
The ready biodegradability of the test substance was determined in a 14 d MITI test (I) according to OECD Guideline 301C (1981) and the EU Method C.7. Both the test substance and reference substance sodium benzoate were tested at a concentration of 100 mg/l. Biodegradation was equivalent to 0 and 91 %, respectively. Under the study conditions, the test substance was not readily biodegradable.
Not readily biodegradable
