“…Results obtained by several authors studying the effect of a widely used surfactant (LAS) on the adsorption of phenanthrene (PAH) on soils indicated a significant increase on the mobility or accumulation of phenanthrene in soils and plants (Yediler et al, 1991;Ou et al, 1995;Xia et al, 2005). The different K d values between PAHs (approximately 250 L/kg) and ENR (3000-6000 L/kg) might be the major reason for the different effects exhibited by the surfactants on the mobility of target organic compounds in soils.…”

“…sodium dodecylbenzenesulfonate (DBS) e.g., a representative of the linear alkylbenzene sulfonate (LAS) family widely used for domestic and industrial purposes is considered to be able to change the characteristics of soil and influence the mobility of pollutants by affecting the adsorption isotherm of the substances in soils (Yediler et al, 1991;Ou et al, 1995;Xia et al, 2005).…”

The leaching behaviors of enrofloxacin (ENR), a fluoroquinolone group antibiotic, in three different standard soils, namely sandy, loamy sand and sandy loam were investigated according to OECD guideline 312. In addition, the effects of tenside, sodium dodecylbenzenesulfonate (DBS) on the mobility of ENR in two different soils were studied. The mobility of ENR in all three standard soils was very similar and was mostly (98%) concentrated on the top 0-5 cm segment of the soils at pH 5.7. The DBS can enhance the mobility of ENR in soils but the impact was in general negligible under the studied conditions.

“…When SDBS was added to the sediment after atrazine, the adsorption of atrazine increased, probably because of the additional partitioning of the material into SDBS hemimicelles on the sediment surface. The conclusion was supported by Ou et al (1995) , who found that linear alkylbenzene sulfonate (LAS), at low concentrations (<50 mg/L), could decrease phenanthrene adsorption onto soil when LAS contacted with the soil before phenanthrene, and vice versa.…”

Effect of Surfactants at Low Concentrations on the Sorption of Atrazine by Natural Sediment

A series of experiments were carried out to determine the effect of surfactants at low concentrations on the sorption of atrazine by natural sediments. With surfactant concentrations ranging from 0 to 20 mg/ L, anionic and cationic surfactants appreciably reduce the adsorption of atrazine, while nonionic surfactant decreases the adsorption of atrazine at concentrations equal to or less than 1 mg/L and increases adsorption at higher concentrations. Desorption of atrazine in the presence of different sodium dodecylbenzene sulfonate (SDBS) concentrations shows that a portion of the bound pesticide resists desorption in the SDBS free system. However, the addition of SDBS accelerates the desorption of atrazine. Furthermore, the nature of sediment and the contacting sequence of SDBS, at 10 mg/L, with the sediment, also influence the adsorption of atrazine. The conclusions in this study could be explained partially by the effect of the type and concentration of surfactants and the characteristics of sediments. Water Environ. Res., 78, 653 (2006).

“…Most of current studies focused on the modification of sorbents, with the concentrations of surfactants much higher than any currently known environmental level, while few studies reported the competitive influence of surfactants on HOCs sorption on soils [17,18]. However, understandings of the effect of surfactant at low concentrations relevant to environment on the HOCs sorption, especially for that on the hydrophilic mineral surface, are still deficient.…”
