Description of key information
A 30% aequous solution of acetoacetamide was tested for inherent biodegradation in the Zahn-Wellens-test by measuring the DOC disappearance. During the first 7 days of the test the DOC exhaustion achieved > 70% of the carbon content of the added test substance, but the following day the rate of degradation staye at the plateau in the range 70 - 72%. The results were confirmed by additionally conducted COD control analyzes. COD at the start was 510 mg/L and 160 mg/L after 28 days, corresponding to an elimination of about 69%.
Acetoacetamide (30% solution) is inherently biodegradable under the conditions of the zahn-Wellens Test.
