- Value:
- 55
- Temp.:
- 20 °C
- Matrix:

- Remarks on result:
- other: pH not determined
Results: Batch equilibrium or other method
- Recovery of test material:
- >90% by precipitation with FeSO4
- Transformation products:
- not measured
Applicant's summary and conclusion
- Validity criteria fulfilled:
- not specified
- Conclusions:
- 55% of a 100 mg/L dye solution adsorbs to sewage sludge (2 g/L). However, 90% of the substance were recovered after a chemical precipitation test with FeSO4 ( 1 g/L). Additionally, adsorption to activated carbon was measured (determined value: 38 mg/L). The general adsorption rate to activated sludge is relatively low and almost fully reversible which corresponds to the low log Kow and the high water solubility.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
