Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Adsorption / desorption
Administrative data
Link to relevant study record(s)
- Endpoint:
- adsorption / desorption: screening
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 121 (Estimation of the Adsorption Coefficient (Koc) on Soil and on Sewage Sludge using High Performance Liquid Chromatography (HPLC))
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- HPLC estimation method
- Media:
- soil
- Test temperature:
- 25degC
- Details on study design: HPLC method:
- Instrument: Agilent 1200 Series Liquid Chromatograph with Chemstation software
Column: Hyperclone CN (CPS) (25 cm x 4.6 mm internal diameter)
Column temp.: 25°C
Mob. phase comp.:Methanol:water (55:45 v/v)
Flow rate: 1.0 ml/min
Injection vol.: 20 µl
Detector: UV set at 210 nm - Key result
- Type:
- log Koc
- Value:
- ca. 3
- Temp.:
- 25 °C
- Validity criteria fulfilled:
- yes
- Conclusions:
- Ferrocene was determined to have a log10Koc value of 3.0 (equivalent Koc value = 1050).
- Executive summary:
A calibration plot of log10k versus log10Kocwas constructed for the reference standards. The logarithm of the capacity factor for the test substance was then calculated and the log10Kocvalue determined by interpolation.
Ferrocene was thus determined to have a log10Kocvalue of 3.0 (equivalent Kocvalue = 1050)

Additional information
In a study performed in OECD 121, Ferrocene was determined to have a log10Kocvalue of 3.0 (equivalent Kocvalue = 1050). (The log10Kocvalue determined by interpolation.)
