Phenanthrene sorption

Fig. 5. Relationship between the log Koc for phenanthrene sorption and the aliphaticity of humic acids, sequentially extracted from a soil. F-l, F-4, F-7, and F-9 are the first, fourth, seventh, and nineth extracted humic acids, respectively. 0.005, 0.05, and 0.5 pg mL are selected liquid-phase equilbrium concentrations of phenanthrene (Kang and Xing 2005).

Neglecting the contribution of adsorption, especially for planar compounds and at low concentrations, may cause substantial underestimation of Kid. This is shown in Illustrative Example 9.2 for phenanthrene sorption to various soils and sediments (Huang et al., 1997).

The ionic strength was 0.1 M NaCI, and the kaolinite concentration was 100 g/L. Error bars are smaller than the symbols. Solid lines are the best fits from linear regression and represent the KD values. Adapted from Ko et...
