Description of key information

Adsorption / desorption

The Koc of the test item was determine using the HPLC method to be 15968 ± 254.8 (95 % confidence interval) and the log Koc to be 4.2 at 25 °C, respectively.

Additional information

The adsorption coefficient (Koc) on soil and sewage sludge of 1,1'-(1,1,2,2-tetramethylethylene)dibenzene was assessed according to EU method C.19 and OECD guideline no. 121 using the HPLC method. Based on the retention time measured for 1,1'-(1,1,2,2-tetramethylethylene)dibenzene (8.25 min), the log Koc was estimated to be 4.20 ± 0.007 (95 % confidence interval) corresponding to a Koc of 15968 ± 254.8 (95 % confidence interval) at 25 °C.
