Description of key information
For the test item the KOC in soil and sewage sludge was determined according to OECD 121 by using the HPLC method. The determined log KOC ranges between 2.43 - 3.28. Column temperature: 30°C
tR mean [min] Capcacity factor k'=(tr-t0)/t0 log k' log Koc
test item Peak 1 (4.2 % area-%) 4.703 0.818 -0.087 2.43
test item Peak 2 (72.3 % area-%) 5.193 1.007 0.003 2.72
test item Peak 3 (23.4 % area-%) 6.507 1.515 0.180 3.28
please note: pH values of solutions could not be determined as pH value is defined for aqueous solutions.
