“…For instance, sorption of toluene and naphthalene on soils was enhanced in the presence of the cationic surfactant CTAB (Zhang and Zen, 2006), while sorption of atrazine (a less hydrophobic chemical) was inhibited by CTAB (Tao et al, 2006). The existence of an anionic surfactant, sodium dodecylbenzene sulfonate (SDBS), enhanced sorption of aniline and pnitrophenol on sediments or soils (Shen et al, 2003), but reduced the sorption of aldicarb (a more hydrophilic pesticide) on soils (Dai et al, 2001). PFOS contains both hydrophobic and hydrophilic moieties, making it different from many other POPs (persistent organic pollutants), therefore, the sorption and desorption behaviors of PFOS are expected to be strongly affected by cationic and anionic surfactants in a different way.…”

a b s t r a c tSorption and desorption of PFOS at water-sediment interfaces were investigated in the presence of a cationic surfactant, cetyltrimethylammonium bromide (CTAB), and an anionic surfactant, sodium dodecylbenzene sulfonate (SDBS). CTAB remarkably enhanced the sorption of PFOS on the sediment. In contrast, the influence of SDBS to the sorption of PFOS was concentration dependent. Two contrasting factors were responsible for the phenomenon. One was the sorption of the surfactant itself to the sediment, which enhanced the sorption of PFOS. The other was the increase in solubility of PFOS caused by the adding of surfactants, which decreased the sorption of PFOS. SDBS had a much lower sorption capacity, but rather strong ability to increase the solubility of PFOS. High levels of SDBS remarkably reduced the sorption of PFOS on the sediment. These results imply that cationic and anionic surfactants may have contrast impacts on the distribution and transport of PFOS in the environment.

“…In this case, sorption was relatively quick which was better described by the Langmuir isotherm model. For the sorption of aldicarb and SDBS on dried soil, a linear sorption isotherm fit the data well (Dai et al 2001). Rodríguez-Cruz et al (2005) studied adsorption of sodium dodecyl sulphate on eighteen soils, indicating that SOM can greatly affect the adsorption capacity.…”

Dodecylbenzene sulfonic acid (DBSA), the acid form of sodium dodecylbenzenesulfonate (SDBS), is often identified and detected in soils. However, it still has less awareness of the sorption behavior of DBSA with soil organic matter. In this paper, the sorption behaviors of DBSA on two different types of soils (Mollisol and Alluvial soils) and soil humic acids (HAs) were studied and compared, and the mechanisms of HAs and DBSA interactions were discussed. Sorption dynamics and isotherms were studied using the batch equilibrium method. The sorption kinetics was relatively slow, and the sorption equilibrium can be reached within 10 h. In the designed concentration range of DBSA in this work, the maximum DBSA sorption capacities on the Alluvial soil HA (AHA) and the Mollisol soil HA (MHA) were 115.0 and 112.2 mg/ g, respectively, which were higher than those of the Alluvial soil (AS) and Mollisol soil (MS). The sorption isotherms were well fitted by the Freundlich equation. The sorption capacity of the AHA was greater than that of the MHA, AS and MS. Furthermore, the sorption complexes of HAs and DBSA were characterized using elemental analysis, micro-Fourier transform infrared spectroscopy (FTIR), solid-state 13 C nuclear magnetic resonance (NMR) spectroscopy and electron spin resonance spectroscopy (ESR), it reveals that the sorption of DBSA on HAs mainly occurred on the C=O, C-O and aromatic functional groups. Moreover, the sorption data indicated that the sorption behavior was complicated, probably due to the formation of H bonds, hydrophobic interactions and electron donoracceptor mechanisms.

“…The effective desorption of BPA from the soil could be explained by the increased solubility of BPA and the change of surface tension in the presence of surfactants. Usually, even at very low concentration, surfactants can reduce the surface tension of soil water to a large extent, which would result in a higher wettability of soil particles [38]. A higher wettability of soil particles would reduce the amount of other pollutants adsorbed by soil and hence enhancing the solubility of BPA.…”
