Description of key information

Adsorption coefficient: The adsorption coefficient of the test item was determined to be > 4.27 x 10E05 with Log10 Koc > 5.63 (OECD 121 and EU Method C.19).

Additional information

Adsorption coefficient

The determination was carried out using the HPLC screening method, designed to be compatible with Method C.19 Adsorption Coefficient of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 121 of the OECD Guidelines for Testing of Chemicals, 22 January 2001.

The test utilised a High Performance Liquid Chromatograph and a commercially available cyanopropyl reverse phase HPLC column containing lipophilic and polar moieties was used. The dead time was determined by measuring the retention time of formamide (purity quoted by supplier: 99.94%) at 820 mg/L in methanol:water (55:45). Solutions of reference standards were prepared in methanol and test item (0.1018 g) was diluted to 10 mL with tetrahydrofuran to give a concentration of 10.2 g/L

 

The adsorption coefficient of the test item was determined to be > 4.27 x 10E05 with Log10 Koc > 5.63.
