for low OC soils could be attributed to H-bond interactions between
phenolic hydroxyl and clay surfaces (clay-content in these soils: 68% and
86%).
This type of adsorption can't be applied to explain the adsorption
phenomenon (correlation between OC-content and adsorption), which
usually occures in standard soils.
Result : Koc = 3420 (Apison), 3350 (Fullerton), 115 (Dormont)
Test condition : 3 soils tested: Dormont (pH 4.2; OC 1.2%), Apison (pH 4.5;
OC 0.11%), Fullerton (pH 4.4; OC 0.05%)
soil/water ratio 1:1 - 1:66
initial TS concentration 0.5 - 1.0 mg/l
incubation period 24 h
Reliability : (3) invalid
No standard soil was used in the test. Soils Apison and Fullerton have a
very low OC-content.Suggested OC-content in OECD 106:0.6-3.5%; in
67/548/EEC C.18: >0.3%) ).

Result : Neither Freundlich adsorption coefficients nor Koc values are reported in
the article. The authors report the isotherms in graphic formate.
In the Chemfate database citation of this article Freundlich adsorption
coefficients (K) are estimated from the isotherms at about 50 ppm: 0.50
E02 to 0.5 E01.
The corresponding Koc values can be calculated as 560 to 10000.
No explanation for the wide variety of the adsorpion coefficients is given.
Test condition : 5 soils were tested: Davidson (pH 6.4; OC 0.3%), Molokai (pH 6.2; 0.5%),
Fanno (pH 7.0; OC 0.9%), Mohave (pH 7.8; OC 0.4%), Ava (pH 4.5; OC
0.4%)
200 ml deionized water were added to 10 g of soil
initial TS concentration 5 - 100 ppm
temperatur 22 °C
equilibration time 5 days
