Description:
The sorption of ionizable organic compounds to sediments and saturated soils is examined. he sorption of pentachlorophenol to two sediment silt-clay fractions as a function of pH is described. Sorption of both the neutral and the ionic species was shown to occur; results were quantitatively interpreted by accounting for sorption of both the neutral and ionic species and by accounting for acid dissociation in the aqueous phase. n addition, factors influencing the sorption of several organic bases to sediments are described, as well as some of the inherent difficulties encountered in applying phenomenological data to distinguish among various physical and chemical processes. inally, processes influencing the distribution of neutral and anionic surfactants are discussed briefly.
