%X An organic-mineral complex of montmorillonite and dissolved organic matter (DOM) was synthesized using trash infiltration fluid as the raw material to extract DOM. The sorption behavior of phenanthrene on the montmorillonite/DOM complex was investigated by varying parameters including temperature, pH, and solid-liquid ratio. The results indicated that the sorption capacity of the montmorillonite/DOM complex for phenanthrene increased dramatically compared with that of pristine montmorillonite; the sorption quantity decreased with increasing temperature, but was barely influenced by pH; the equilibrium sorption capacities decreased, while the sorption efficiencies increased with increasing solid/liquid ratio. In addition, the kinetic data of phenanthrene sorption by the montmorillonite/DOM complex were fit well by the Henry equation and the Freundlich equation. Moreover, desorption experiments of phenanthrene on the montmorillonite/ DOM complex demonstrated that phenanthrene has good sorption stability on the complex.
