| Abstract | ||
| Abstract The extensive utilization of hydrophobic organic compounds such as surfactants generates high environmental pollution levels. Due to their hydrophobicity, this type of compound tends to accumulate in soil organic matter. Distribution coefficient (Kd), Freundlich adsorption coefficient (Kf) and Langmuir adsorption coefficient (KL¬) for adsorption of Triton X-100 on three agricultural soil samples with different characteristics were determined. Adsorption of Triton X-100 in solutions was best fitted to the Freundlich equation. The effects of soil organic matter (OM) content, soil clay content and exchangeable cation content of natural soils on the adsorption capacity of Triton X-100 in water-solid systems were investigated based on the adsorption isotherm analysis. Results showed that, values of Kd and Kf increased with increasing soil OM content, but varied irregularly with clay content, exchangeable cations and pH. | ||
