摘要

Recently, Schrap and co-workers reported experimen-tal hexachlorobenzene partition coefficients (K_p~(exp), L/kg) at varying sediment/water ratios (S, kg/L). To correct for the artefact of incomplete phase separation [2], three methods were evaluated: (a) a method based on the dry weight of the nonseparable phase (the third phase), (b) a method based on the carbon content of the third phase (DOC, kg/L), and (c) a method based on apparent enhanced solubilities. The K_p~(exp) values were corrected using the Gschwend and Wu model. Schrap et al. concluded that method (c) was the most successful. I have two comments on their modeling approach. In the following explanation their nomenclature is followed.
