1) Key: HPLC adsorption-desorption study, 2010, K1, OECD & GLP; Log Koc ranged from 4.39 to 4.95 for the 3 main constituents of the substance
The adsorption coefficient (Koc) was derived according to the OECD 121
(HPLC) & GLP guidelines (Drake, 2010). Chemical standards with log Koc
values ranging from 1.32 to 5.63 were employed to calibrate
instrumentation. The log Koc values derived for the 3 main constituents
are 4.39, 4.66 and 4.95 for R-59, R-1679 and R-898 respectively
(measured at 20°C).
The reported log Koc value for DAPD reported, 4.66, was calculated as
the average of the log Koc of the 3 main constituents.
